CERN Accelerating science

Part of the CMS collaboration’s commitment to the ongoing experiments at the LHC is to participate in the detector shifts which occur 24 hours a day, seven days a week.

CMS has published its first paper on proton-lead (pPb) collisions, describing the observation of a phenomenon that was previously seen first in nucleus-nucleus collisions but also detected by CMS in proton-proton (pp) collisions.

All of the atoms in our bodies are made of electrons, protons and neutrons, and the protons and neutrons can be further broken down into quarks. Fundamentally, then, we are made of only two types of particles: electrons and quarks. But what do these labels mean?

Visitors to P5 now have a series of seven posters of beautiful 3D drawings of the CMS detector to look at before they go underground to the CMS cavern.

This series of the drawings is called “ZOOOM”.

Our best understanding of the early Universe tells us that a dense medium, known as the quark-gluon plasma (QGP), existed in the first microseconds after the big bang.

Guido Tonelli, CMS Spokesperson 2010–2011, was made 'Commendatore' of the Order of Merit of the Italian Republlic (Commendatore Ordine al Merito della Repubblica It

The CMS Letter of Intent was completed 20 years ago this month.

You may view it or subscribe to it in a variety of ways, as well as to a number of sub-group calendars (Run Coordination, Upgrades, Publications, etc.), as follows:

The LHC circulates protons inside its beam-pipes not in a continuous stream but in several very closely packed bunches.
