In 2011, CMS presented early evidence that Upsilon (Υ) particles produced in lead-lead collisions “melt” as a consequence of interacting with the hot nuclear matter created in these heavy-ion interactions. CMS has since updated and extended this...

In the vast particle landscape, there are, to borrow a phrase, known knowns (the Standard Model, for example), unknown unknowns (exotic extensions of the Standard Model and beyond), and those ever-interesting known unknowns. A recent CMS observation...

Collaborations of high-energy physicists often number in the thousands, and this presents some unique challenges. “CMS is a big collaboration, with 3,000 people from diverse backgrounds, speaking different languages,” says Sudhir Malik, co-convener...

At the Hadron Collider Physics (HCP) Symposium held in Kyoto, Japan on 12–16 November 2012, CMS presented many new results, including updates on the search for the Standard Model (SM) Higgs boson as well as Supersymmetry (SUSY). Several of these...

After three years of very successful operation that led to the discovery of a new boson in 2012, the LHC is scheduled for a series of upgrades that will enhance the experimental potential to study the nature of the new particle, and to extend the...

Amongst all known elementary particles, the top quark is peculiar: weighing as much as a Tungsten atom, it completes the so-called 3rd generation of quarks and is the only quark whose properties can be directly measured. Owing to its mass, the top...

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. Many researchers spend time in the CMS Control Room located in Cessy, France,...

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. The effect is a...

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...

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. These early-Universe conditions can be mimicked in particle colliders by smashing...
