LHC upgrade to open up ‘new realm of particle physics’

April 2, 2013

1

Engineers have begun a major upgrade of the Large Hadron Collider (LHC). Their work should double the energy of what’s already the most powerful particle accelerator in the world. BBC News is the first to be allowed to see inside the LHC – on the French-Swiss border – to watch the work being carried out. […]

Physicists unveil plans for ‘LEP3′ collider at CERN

August 9, 2012

0

A group of physicists from Switzerland, Japan, Russia, US and the UK has proposed using the tunnel that currently houses the Large Hadron Collider (LHC) at the CERN particle-physics lab near Geneva for a dedicated machine to study the Higgs boson. The facility, dubbed LEP3, is named after CERN’s previous accelerator, the Large Electron–Positron Collider […]

press here: CERN webcast (update) CERN experiments observe particle consistent with long-sought Higgs boson Geneva, 4 July 2012. At a seminar held at CERN today as a curtain raiser to the year’s major particle physics conference, ICHEP2012 in Melbourne, the ATLAS and CMS experiments presented their latest preliminary results in the search for the long sought […]

Is the moon full? Just ask the LHC operators

June 8, 2012

Last weekend, I had the pleasure to be shift leader for ATLAS. It was a real pleasure for many reasons: being right in the middle of the action, surrounded by an international team of enthusiastic and dedicated people, and taking part in great teamwork. The shift crew (about ten people plus dozens of experts on […]

New CERN Results On Rare B Decays

June 8, 2012

0

A Tombstone To SUSY ?  The CERN average of searches for rare B decays to muon pairs has been shown yesterday in a talk given by Mitesh Patel at the “Physics at the LHC” conference, which is being held in Vancouver (BC) this week. And the results are not very encouraging for supporters of Supersymmetry: the […]

LHCb experiment squeezes the space for expected new physics

March 5, 2012

0

Geneva, 5 March 2012. Results presented by the LHCb collaboration this evening at the annual ‘Rencontres de Moriond’ conference, held this year in La Thuile, Italy, have put one of the most stringent limits to date on the current theory of particle physics, the Standard Model. LHCb tests the Standard Model by measuring extremely rare […]

Searching for Higgs: from LEP towards LHC

December 23, 2011

0

W.-D. Schlatter (CERN), P. M. Zerwas (DESY) After a brief introduction to the theoretical basis of the Higgs mechanism for generating the masses of elementary particles, the experimental searches for Higgs particles will be summarized, from bounds at LEP to inferences for LHC. The report will focus on the Standard Model, though some central results […]

LHC reports discovery of its first new particle

December 22, 2011

0

The Large Hadron Collider (LHC) on the Franco-Swiss border has made its first clear observation of a new particle since opening in 2009. Known as Chi-b (3P), it is a boson – the label given to particles that can carry the forces of nature. The as-yet unpublished discovery isreported on the Arxiv pre-print server. The […]

LHC proton run for 2011 reaches successful conclusion

October 31, 2011

Geneva, 31 October 2011. After some 180 days of running and four hundred trillion (4×1014) proton proton collisions, the LHC’s 2011 proton run came to an end at 5.15pm yesterday evening. For the second year running, the LHC team has largely surpassed its operational objectives, steadily increasing the rate at which the LHC has delivered […]

Scientists at Cern’s Large Hadron Collider near end of the search for the Higgs boson

October 9, 2011

For almost 20 years, Bill Murray has been hunting the Higgs boson, the elusive subatomic particle that is thought to give mass to the basic building blocks of nature. In those two decades, the 45-year-old Edinburgh-born researcher has watched the search for the holy grail of physics narrow to a tighter and tighter group of […]

Is The Higgs Boson Somewhere Inside Your iphone?

LHSee: discover what happen at the LHC. Want to find out how to Hunt the Higgs Boson using your phone? Ever wondered how the Large Hadron Collider experiments work, and what the collisions look like? Scientists at the world’s biggest scientific experiment – the Large Hadron Collider at CERN, Geneva – are trying to answer […]

Making CERN’s best even better

September 29, 2011

CERN’s Large Hadron Collider is finally up and running, but the lab is already planning an audacious upgrade using technology not yet invented, as Matthew Chalmers reports It is hard to imagine upgrading an instrument as big and complex as the SwFr6.5bn (€10bn) Large Hadron Collider (LHC) at the CERN particle-physics lab near Geneva. The […]

Dimension-hop may allow neutrinos to cheat light speed

September 23, 2011

0

A CERN experiment claims to have caught neutrinos breaking the universe’s most fundamental speed limit. The ghostly subatomic particles seem to have zipped faster than light from the particle physics laboratory near Geneva, Switzerland, to a detector in Italy. Fish that physics textbook back out of the wastebasket, though: the new result contradicts previous measurements […]

Neutrinos Travel Faster Than Light, According to One Experiment

Read also: A Six-Sigma Signal Of Superluminal Neutrinos From Opera! If it’s true, it will mark the biggest discovery in physics in the past half-century: Elusive, nearly massless subatomic particles called neutrinos appear to travel just faster than light, a team of physicists in Europe reports. If so, the observation would wreck Einstein’s theory of […]

Month-end target mooted for finding “no Higgs”

September 6, 2011

0

U.S.-based physicists said on Monday they hope to have enough data by the end of this month to establish if the elusive Higgs boson, a particle thought to have made the universe possible, exists in its long-predicted form. If the answer is no, scientists around the globe will have to rethink the 40-year-old Standard Model […]

Higgs boson signals fade at Large Hadron Collider

Cern scientist says he sees ‘no striking evidence of anything that could resemble a discovery’ in hunt for Higgs boson Ripples of excitement swept through the physics community last month when Cern scientists reported what looked like glimpses of the long-sought Higgs boson. But the hopes have been dashed as it was revealed that the tantalising hints had all but […]

Geneva, 17 June 2011. Today at around 10:50 CEST, the amount of data accumulated by LHC experiments ATLAS and CMS clicked over from 0.999 to 1 inverse femtobarn, signalling an important milestone in the experiments’ quest for new physics. The number signifies a quantity physicists call integrated luminosity, which is a measure of the total […]
