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 of the CMS Data Analysis School (CMSDAS).

New CMS Results at HCP

Kyoto, Japan on 12–16 November 2012

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 searches for new physics beyond the Standard Model

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.

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.

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

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

I have been a physicist working for CMS for about ten years now, and a guitarist for about twice as long. From time to time I have tried to somehow marry these two worlds, and when I became interested in guitar building I realised that I need to build a “CMS guitar”.

Every year CERN opens its doors to hundreds of high-school students who wish to get an in-depth look at what it is like to be a scientist or engineer at one of the world’s most prestigious research laboratories.

CMS has just passed another major milestone, recording more than 10 inverse femtobarns of data at 8 TeV.

Despite higher pile-up creating more complicated events, CMS improved its running efficiency and now regularly achieves efficiencies in excess of 95, 97 or even 98% each day.

Jets are the experimental signatures of quarks and gluons produced in high-energy processes such as head-on proton-proton collisions.

Our understanding of physical reality — of everything and nothing — has changed forever. We don't yet know where we are heading, but nothing will ever be the same. As a scientist, I don't know what more I could ask for.

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 why there is diversity and life in the universe.

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

CMS 2012 data exceed 2011 sample

LHC has delivered 6.65 fb−1 of collisions to CMS in 2012 so far

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.

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.
