An application using real event data from CMS has won “Best Science” prize in a public “Science Hack Day” held in Nairobi between 13th and 15th April 2012. Science Hack days bring together a wide range of enthusiastic members of the public to…

Tejinder (Jim) Virdee, CMS co-founder and former Spokesperson (2006-2010), was today elected as Fellow of the prestigious Royal Society of the UK. Royal society fellows are “the most eminent scientists, engineers and technologists from the UK and…

The Year-End Technical Stop or YETS, when the LHC takes its annual break, seemed like a quiet time to those outside CERN. After all, there were no collisions taking place and the CMS detector was not operating 24-hours-a-day, seven-days-a-week.…

A new year with new energy and new luminosities: 2012 holds the promise to close the question on the existence (or absence) of a Standard Model Higgs boson. Besides the obvious challenges posed by the LHC restart at a higher energy and a much…

As high-energy particle physics pushes exploration at energy and luminosity frontiers, experiments are becoming increasingly complex – and this, in turn, drives the need for developments in particle detectors and their associated technologies.…

The Large Hadron Collider has woken from its winter slumber with a bang. Just after midnight local time on 5 April, the world's most powerful particle accelerator, based near Geneva, Switzerland, shattered its own world record by smashing protons…

THE world's largest particle collider notched up a new record yesterday as it escalated its quest to explore the origins of the Universe.

The Large Hadron Collider (LHC) is operating again after its winter break.

A search is presented for a massive particle, generically referred to as a Z′, decaying into a t-tbar pair. The search focuses on Z′ resonances that are sufficiently massive to produce highly Lorentz-boosted top quarks, which yield collimated decay…

The production of b jets in association with a Z/γ* boson is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV and recorded by the CMS detector. The inclusive production rates for Z/γ* + b-jet is…

The DT upgrade pages has been updated to include new links to many items such as meetings, documents, results and so on. See: https://cmsexperiment.web.cern.ch/org/dt-upgrades -- Cristina Fernández Bedoya

CMS has just recorded the first collisions with stable beams at a world-record collision energy of 8 TeV[1]. CMS took good quality data with all sub-detectors working well. The LHC fill lasted for 1h34min and the "pile-up" at the beginning of the…
