A reminder on CERN Safety rules

The Top quark is the heaviest of the six quarks of the Standard Model and was discovered only 16 years ago by the Tevatron experiments at Fermilab. In addition to the usual production of Top-AntiTop pairs in accordance with quantum chromodynamics (…

Read the paper: SUS-11-003 The analysis shows no excess of events over the Standard Model expectations. As a result, exclusion limits were placed on searches for squarks and gluinos in the Constrained Minimal Supersymmetric extension of the Standard…

It is well known that CERN is an open laboratory, welcoming visitors from around the world on a daily basis. Often these visits are organised by schools or colleges, or are simply part of a family vacation to the Geneva area. Many VIPs also visit,…

The hunt for the Higgs particle is well ahead of schedule, say researchers at the Large Hadron Collider (LHC). Earlier this year they said they would either discover the Higgs or confirm it does not exist by the end of 2012. Now, because the machine…

The latest results from the Large Hadron Collider serve as a reality check for expectations that radical scientific discoveries are just around the corner. A month ago, folks were buzzing about prospects that the elusive Higgs boson might soon be…

A few years ago, celebrated British physicist Stephen Hawking was widely reported in the press to have placed a provocative public bet that the LHC (along with all particle accelerators that preceded it) would never find the Higgs boson, the so-…

Scientists at the Large Hadron Collider have reported another twist in their search for the "God Particle" after signals that they hoped might lead them to the Higgs boson disappeared. [...]

The Higgs boson, the most sought-after particle in all of physics, is proving tougher to find than physicists had hoped. [...]

Scientists at the Large Hadron Collider say a signal that suggested they might have seen "hints" of the long-sought Higgs boson particle has weakened. [...]

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…

Read the paper: TOP-11-003 The measured production rates of Top-antiTop pairs, where one lepton and four jets of particles is observed in the final state, show good agreement with Quantum Chromodynamics (QCD), the theory of the strong interaction.…
