A never-before-seen subatomic particle has popped into existence inside the world's largest atom smasher, bringing physicists a step closer to unraveling the mystery of how matter is put together in the universe.

Physicists using the Large Hadron Collider (LHC) particle accelerator have discovered their first brand-new baryon, a particle consisting of three quarks.

It has not discovered the Higgs Boson — not yet, anyway — but the Large Hadron Collider (LHC) particle accelerator has revealed a never-before-discovered particle comprised of three quarks.

Scientists running the Large Hadron Collider, aka the "big bang machine", announced Friday they've discovered a brand new particle during one of their experiments.

No, unfortunately not yet the discovery of the century. Still, the new particle found by CMS in its 2011 dataset is a very important piece of the puzzle of low-energy spectroscopy. Here "low" should be taken with a pinch of salt: the new particle,…

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…
