LHC finds a new and very charming particle: the Xicc++ baryon

What happens if you get two charm quarks together in one baryon? Something four times as heavy as a proton that can help the world understand the strong nuclear force, according to boffins at the Large Hadron Collider. Last week, CERN announced the first “unambiguous” observation of a particle comprising the two charm quarks …

Boffins gently wake the Large Hadron Collider from annual hibernation

CERN says the restart process for the Large Hadron Collider is complete and the proton-smasher is ready to start its 2017 science program. Alas, Vulture South's favourite mental image of an Igor saying “Yeth, marthter” and hauling on suitably Big Red Switch doesn't match reality: the restart process is a carefully-managed …

Colliders, containers, dark matter: The CERN atom smasher's careful cloud revolution

CERN made headlines with the discovery by physicists in 2012 of the Higgs boson, paving the way to a breakthrough in our understanding of how fundamental particles interact. Central to this was the Large Hadron Collider – a 26km ring of interconnected magnets chilled to -271.3C straddling the Franco-Swiss border. The LHC is …

Large Hadron Collider turns up five new particles

Boffins poring over data from the Large Hadron Collider's “Beauty” experiment are blinking in surprise, having turned up five new particles in one hit. The “hiding in plain sight” articles in data from the "LHCb" are all excited states of the baryon Omega-c-zero, Ωc0, and the CERN boffins saw the five new particles from its …

CERN boffins see strange ... oh, wait, that's just New Zealand moving 2m north

New Zealand's been hit by two nearly-simultaneous earthquakes that left two people dead, isolated some towns, cut telecommunications links – and rattled the Large Hadron Collider near Geneva. The quake might also inconvenience infosec types visiting the country for one of the Southern Hemisphere's pre-eminent conferences, …

Sorry, say boffins, the LHC still hasn't sucked us into a black hole

The Large Hadron Collider (LHC) has still failed to produce microscopic black holes, according to a new analysis of data from the Compact Muon Solenoid (CMS) collaboration. The idea, beloved of theoretical physicists, lawyers, and cranks others, is that collisions even down to the Tera-electron-volt (TeV) scale could produce …

Large Hadron Collider gives young ALICE a black-hole ray gun

CERN's Large Hadron Collider is ready to provide more scientific breakthroughs to the world after almost two years of slumber and months of recommissioning. Particle-physics boffins tell us the new LHC experiments are "ready to take data at the unprecedented energy of 13 TeV (trillion electron volts), almost double the …

Boffins: Large Hadron Collider NOW movin', we're getting down and crush groovin'

The world's mightiest particle accelerator was resurrected this morning, following a two-year shutdown to upgrade the proton-shattering Large Hadron Collider. The LHC, which is based at CERN in Geneva, Switzerland, was brought back into operation earlier today. Scientists said that two proton beams were circulated in opposite …

Short circuit at Large Hadron Collider slows return to matter-mauling

The eager Igors of CERN are going to have to wait a little longer before they try to destroy the universe: it turns out that the upgraded Large Hadron Collider (LHC) has a short circuit in one of its dipole circuits. Mere days before the LHC's keenly-anticipated Earthproton-shattering return to operations, the main dipole …

Boffins grasp Big Knob, get ready to go ALL THE WAY at the LHC proton-punisher

Boffins at CERN are counting down the days until the rebuilt and now even more powerful Large Hadron Collider (LHC) particle accelerator restarts this spring, following a two-year-long shut down. Until this point, the LHC's power had been intentionally limited for safety reasons, but now its fullawesome power can be unleashed …

Hunt for Higgs Boson and dark matter now starts ON YOUR SOFA

If you're not too busy this weekend, why not sit down on your sofa and try to find a Higgs Boson or dark matter? The idea's feasible because CERN yesterday released data generated by the the Compact Muon Solenoid (CMS). “one of two large general-purpose particle physics detectors” at the Large Hadron Collider. CERN says the …

CERN's 2014 Xmas gift from the Large Hadron Collider: Two new baryons

Analysis of Large Hadron Collider data collected in 2011 and 2012 has turned up two new subatomic particles: a couple of baryons that are six times as massive as a proton. The atom-smasher's LHCb experiment produced data that looks a lot like particles designated Xi_b'- and Xi_b*- which were first predicted by Canadian …

No, pesky lawyers, particle colliders WON'T destroy the Earth

A couple of lawyers are calling for the US government not to fund any further research at one of its premier heavy-ion colliders, the RHIC, because of a discredited 15-year-old “doomsday scenario” debate. Alert readers will recall that back in 2008, botanist Walter L Wagner had a court case against the Large Hadron Collider …

Hadron Collider urinal cake tale wins El Reg's LHC book giveaway

Compo Entrants to our soaraway somewhat-Hadron-Collider-themed writing competition have been biting their nails all week, desperate to know who has scooped the awesome "Large Hadron Collider Pop-Up Book: Voyage to the Heart of the Matter" prize. But now, their wait is over. The Reg can announce that the winner of a gleaming free …

Exotic physics takes an arrow to the knee with new ATLAS results

Far from being the death of physics, the discovery of the Higgs boson in 2012 has set physics on a bunch of new searches – including how the Higgs decays. Because Standard Model physicists were confident that the Higgs would be found, decades' worth of work await to figure out what particles it would decay into. That decay …

Stephen Hawking: 'Boring' Higgs Boson discovery cost me $100

Stephen Hawking hijacked an event at the Science Museum to tell the world he thinks the Higgs Boson has made physics a boring subject. The celebrated boffin has a long-standing rivalry with Nobel Prize-winner Professor Peter Higgs, who gave his name to the famous "God Particle". At an event in London's Science Museum to …

Google adds Large Hadron Collider tunnel to Street View

Google has dragged is Street View imaging kit to Switzerland, then lugged it beneath the earth to capture images of the tunnel containing CERN's Large Hadron Collider (LHC). Sadly the images don't quite let you be the atom, instead offering the chance to trundle through the LHC's long and monotonous tunnel. CERN's head of …

Rackspace, CERN partner on OpenStack projects

Sure, hyperscale data center operators may cope with hellacious big data problems as they spy on everything we do on the intertubes, but what about the poor men and women who have to drink from the data firehose that CERN's Large Hadron Collider spews as it works to rip apart the fabric of space and time? Well, thankfully, they' …
