Signaling a likely end to one of the longest, most expensive searches in the history of science, physicists said Wednesday that they had discovered a new subatomic particle that looks for all the world like the Higgs boson, a key to understanding…

Cern scientists reporting from the Large Hadron Collider (LHC) have claimed the discovery of a new particle consistent with the Higgs boson.

The Higgs boson is a particle associated with the electroweak-symmetry breaking mechanism that was proposed in the 1960s and is a vital component of the Standard Model of particle physics. It is believed that all fundamental particles in the known…

On 4th July, at 09:00 CEST, CMS will present their latest results on the search for the Standard Model (SM) Higgs boson at the LHC. The presentation, which is followed by one from the ATLAS collaboration, will be in CERN’s Main Auditorium, and will…

The LHC began its 2012 run in early April, colliding protons at a world-record centre-of-mass energy of 8 TeV[1]. In just over two months, CMS has recorded more data than in the 2011 run. As of the short technical stop starting June 18, the LHC…

Learner Objectives for Masterclass These are educational goals for students participating in the masterclass. Describe/show how conservation laws, behavior of particles in a magnetic field and energy-mass conversion apply to particle physics.…

If you are a student, please show this page to your teacher, and he/she would need to register your class/group. If you are a teacher and you would like to organise a masterclass for your students/teachers, please follow the steps: Read What is the…

While the LHC will play the starring role in the 2013/2014 Long Shutdown (LS1), the break will also be a chance for its experiments to upgrade their detectors. CMS will be expanding its current muon detection systems, fitting 72 new cathode strip…

The search for microscopic black holes at the LHC is motivated by the hierarchy problem — the huge observed difference between the strengths of the electroweak and gravitational forces. The ADD model (Arkani-Hamed, Dimopoulos, and Dvali) offers an…

On request of the FSQ PAG a run with very low pile-up (PU = 0.037) was taken for minimum bias and underlying event studies. Trigger information was exchanged between CMS and TOTEM and a common dataset has been obtained.
