Large Hadron Collider to increase beam energy: Higgs boson can run, not hide
We've seen the Large Hadron Collider running at a record-breaking 7 TeV for short periods, but now CERN is turning it up a notch (to 4 TeV from 3.5) for the rest of the year. The decision comes after an annual performance workshop last week in Chamonix and a report from the CERN Machine Advisory Committee (CMAC). The increase may seem modest compared to the knee-trembling levels of 7 TeV, but it's all part of a broader optimization strategy. Scientists state the new approach should increase the data collected in 2012 to 15 inverse femtobarns -- a three-fold jump from 2011. Even more encouraging is a statement from CERN's Research Director, Sergio Bertolucci, who claims that we should finally know for sure about the existence of the Higgs boson -- either way -- before the LHC enters a temporary shut-down period at the end of the year. Beam yourself over the break for the full press release.
CERN: 'Don't believe the Higgs-Boson hype' (update: not yet)
CERN is pouring cold water on the rumor it's gonna announce the discovery of the Higgs at today's seminar in Zurich. For the uninitiated: the Higgs-Boson is the particle that is believed to give all things mass: it surrounds us, penetrates us and binds the galaxy together. The scuttlebutt is that the ATLAS sensor picked up a Higgs with a mass of 125GeV (gigaelectronvolts) and rated at three-point-five-sigma -- a one sigma barely warrants a mention, a five-sigma is a bona-fide scientific discovery. CERN hasn't confirmed or denied anything, claiming it's still got five inverse femtobarns worth of data (roughly 5 x 70 x 10^12 of individual collisions) to examine before it can be sure, so just chuck the one bottle of champagne into the refrigerator -- better to be safe, eh? Update: Looks like we don't need to bust out the bubbly, after all. The conclusion from the two-hour presentation is that the ATLAS detector has been able to narrow down the region it believes the Higgs is in to 115.5GeV to 131GeV and that any discovery so-far only has a rating of two point three sigma. The CMS is similarly inconclusive, with results bobbing around the two sigma region. In short, whilst they know where they should look, they haven't been able to find one -- yet.
15 Minutes of Fame: Searching for the Higgs boson and a Swift White Hawkstrider
From Hollywood celebrities to the guy next door, millions of people have made World of Warcraft a part of their lives. How do you play WoW? We're giving each approach its own 15 Minutes of Fame. We interrupt our two-part interview with actor Kristian Nairn (Hodor in HBO's blockbuster new series, Game of Thrones) for a quick chat with ... a particle physicist at CERN, the world's largest particle physics laboratory in Geneva, Switzerland. Writes in-game buddy Fra (and thanks, Fra -- much love for all the EU players who brave the whole second language thing to send in tips!), "I have a friend which might be material for one of your interviews (which are great!). He is both good as a healer as he is a physicist. He also does some guides and public talks about his studies, and he is comprehensible even for a dumbass as me. :) I'm pretty sure you've a lot of nerds on your interview list, but a physicist working in one of the most famous labs is something ... new? He also does a lot of jokes about the not-so-good physics in game, or when people care of maximizing numbers that do not really change your game performance if you do all the math." A particle physicist who isn't into theorycrafting? We simply had to know more. Follow us past the break to learn how searching for the Higgs boson is like farming for a Swift White Hawkstrider (and come back next week for more with Game of Thrones' Kristian Nairn).
Large Hadron Collider smashes beam intensity record, inches closer to discovering God particle
Already a record holder for mashing protons together at 7 TeV (trillion electron volts), the Large Hadron Collider can now add world's brightest beam to its list of accomplishments. Beam intensity is a way of measuring the number of collisions in its 17-mile-long track, and a higher intensity means more impacts -- which, in turn, means more data, increasing the likelihood that the elusive Higgs boson will rear its head (should such a thing exist). The LHC smashed the previous luminosity record set last year by the Tevatron collider. What's next for the CERN team, with two world records under its belt? Largest beard of bees.
Has the Higgs Boson been discovered by LHC rival? Are we still here? (Update: No Higgs discovery, and we're still here)
The Large Hadron Collider isn't the only bad boy on the block looking for the so-called God particle -- technically known as the Higgs Boson. A lesser known facility, the Tevatron -- located at the Fermi National Accelerator Laboratory in Batavia, Illinois -- has also been furiously searching for the particle which would help to explain the origins of mass in the universe -- and it looks like they might have found it. A rumor has been swirling about recently that the found particle is a "three-sigma," meaning that it's got a 99.7 percent statistical likelihood of being correct -- but the lab itself has yet to confirm or deny. The Tevatron, which was completed 27 years ago, is the second largest accelerator in the world (after the LHC) and it's expected to be retired once the CERN facility is fully operational. Update: Well, that was fun for the few hours that it lasted. New Scientist has published a piece confirming that Tevatron is in fact denying the rumor, and no Higgs Boson discovery has gone down.
LHCsound brings the noise, asks how low Higgs boson can go
God particle. The Champagne bottle boson. Non-existon. Mysteron. The Higgs boson particle is certainly known by a lot of names, and now we can add another to the list: rock god. The UK's Science and Technology Facilities Council has created "LHCsound: the sound of science." It's a series of (confusingly organized) pages offering acoustic renditions of the Large Hadron Collider's greatest hits, like proton collision, detector sweeps, and, our favorite, simulated Higgs Boson delay, which you can hear after the break. The data created by the energy and frequency of particle decay is used to modify the sound of running water, resulting in a generally creepy effect. We think it'd be perfect for accompanying your next foggy exploration of Silent Hill, but perhaps the next episode of Half Life 2 would be more appropriate.[Thanks, John C.]
Large Hadron Collider to search for God Particle using 7 TeV proton collisions, via live webcast (update: first collisions, video!)
The Large Hadron Collider is about to turn useful, people. Having recently jacked up its particle acceleration power to create 3.5 TeV (trillion electron volts) collisions, the researchers are today pressing ahead with plans to go to a full 7 TeV, which -- you won't be surprised to hear -- has never been done before. Provided the requisite 3.5 TeV per beam is reached, sustained and properly channeled into creating useful collisions, CERN will finally have the data it needs to start its long-awaited physics program based off the findings provided by the LHC. Best of all? The latest world record attempt is being broadcast live over the web right now so why not hit up that link below to witness some history in the making? Update: The momentous first protonic collisions at 7 TeV have just taken place, at just past 1PM CET. Now the time comes for researchers to parse all the incoming raw data, pore over it, analyze it, etc. We'll leave that to them, it's not like you can expect the God Particle to be discovered instantly. To fill the time, we invite you to come past the break for our blow-by-blow updating adventure from this morning plus video of the big moment.
Report: Large Hadron Collider producing tons of awesome collisions
Hey, now, this is some great news, right? The trouble-plagued Large Hadron Collider looks to be doing a bang up job in some of its primary tasks. After breaking the energy record previously held by the Tevatron particle accelerator back at the end of November, 2009, reports are now coming in that the LHC is, in fact, producing some extremely high energy collisions. A research team led by MIT, CERN and the KFKI Research Institute for Particle and Nuclear Physics in Budapest, Hungary have released a report detailing findings that the collisions are producing an "unexpectedly" high number of particles called mesons, subatomic particles composed of one quark and one antiquark. The research is considered one of the first steps in the search for rarer particles, and the elusive, theoretical Higgs Boson. The paper, published in the Journal of High Energy Physics has led scientists to fine-tuning their predictive models for how many mesons will be found in even higher energy collisions.

Large Hadron Collider schedules holiday for 2012, full 7 TeV power for 2013
It's good to know that even huge inanimate objects appreciate the need for a work-life balance. After a nice winter hiatus, Switzerland's Large Hadron Collider is coming back online soon, set to resume smashing protonic beams at one another with the force of 3.5 trillion electron-volts (TeV) per beam, or 7 TeV in total. We have to swallow hard when we hear such force described as "low-energy," but that's what the LHC designers consider it, and moreover we're learning they'll skip past the middle and go for the full 14 TeV potential smashes after a retooling break during 2012. Although this may delay the discovery of the Higgs boson particle, other physics research shouldn't be stalled in the meantime -- scientists claim they'll be able to extract data from the low-energy collisions that could lend us more information on aspects of string theory, extra dimensions, and supersymmetry. Doesn't all this sound like nerds trying to avoid getting real jobs?
Large Hadron Collider reboots, makes first protonic bang!
Yes, ladies and gentlemen, that most epic triumph of human engineering and physics research has finally taken place, and strangely enough our planet's still in one piece too. The search for the Higgs boson particle resumed yesterday, somewhere under the Franco-Swiss border, with the CERN research team successfully executing what the LHC was built to do -- accelerating proton beams to nearly the speed of light, then filming the wreckage as they crash into each other. Having encountered a number of bumps in the road, the researchers have had to significantly scale down the energy at which their early collisions will take place, with the very first ones said to have happened at 900 billion electron volts. Still, plans are afoot for an imminent shift up to 1.2 trillion electron volts (TeV), which would be the highest energy level any particle accelerator has achieved yet, before a ramp up to 7 TeV over the coming year if all goes well.
Large Hadron Collider is online, Higgs boson be damned
"We have captured it! First circulating beam of 2009!" And with that tweet, researchers at CERN announced that they did in fact activate the Large Hadron Collider, after quite a long delay and despite warnings of a looming, nefarious Higgs boson. Whether or not we will have had total destruction as an unfortunate result of the device remains to be seen, but should the future find a way to either cease to exist or travel to the past in some time-bending paradox, we only hope linguists and physicists can work together and figure out the proper verb conjugations for this brave new world.
World to end Wednesday
Well, not really -- the actual experiments that could result in potentially disastrous "micro black holes" won't happen for another month (and probably won't end anything except the lives of a few protons), but as rumored, CERN's flipping the switch on the four billion dollar Large Hadron Collider this Wednesday to test the superconducting magnets that control the proton beams. After a clockwise test, they'll send protons counter-clockwise, and after that -- smashy time. Of course, there are still paranoid lawsuits pending to shut all this down, and we wouldn't mind another rap video or two, but after two decades of work, it's probably time to boot this thing up, death threats or no. Let's make it a good last month of humanity, people.
