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.…

The number of events that an experiment observes is proportional to a quantity called the luminosity — a measure of how many collisions are occurring in the detector. An accelerator operating at high luminosity stands the best chance of producing…

This year's HCAL test beam run in July was completely devoted to studies of hardware that will be used in the upcoming upgrades. During the course of the two weeks the detector was moved in two independent setups – HF and the combined EB+HB+HO –…

High-energy collisions with final states that include leptons (electrons, muons or taus) have played major roles in the history of physics. Several particles – such as J/ψ, W, and Z – as well as productions of pairs of Top quarks were discovered in…

CMS published its 100th paper on 3rd August. This accomplishment, unprecedented in its pace, came as a result of many things working together extremely well. Primarily, the performance of the LHC accelerator during the last two years was terrific.…

Once more a reminder of the Lepton-Photon approvals, which will start in less than a week from now. The INDICO agenda, now with rooms and EVO booking info, can be found here: https://indico.cern.ch/conferenceDisplay.py?confId=149749 At the top of…

CERN, focus of research into the Big Bang and what makes the universe tick, on Thursday announced a new program -- fusing science with art to encourage painting and music inspired by the wonders of the cosmos.
