Colliding different particle species: the LHC’s proton-lead run
The new year brings a new type of collision at the LHC: the accelerator will smash protons and lead nuclei together, allowing CMS and the other LHC experiments to study the cold nuclear matter we expect these collisions to produce.

CMS observes melting of Upsilon particles in heavy-ion collisions
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 observes unexplained particle states
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.

CMSDASia: First CMS Data Analysis School held in Asia
Collaborations of high-energy physicists often number in the thousands, and this presents some unique challenges.

CMS prepares for Pixel and HCAL upgrades
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.

Precision measurements using top quarks at CMS
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.

CMS Control Room: a perfect venue for Friday nights!
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.
