LHC access required: Time estimate ~ 2 years
On Saturday at 8.25am the shift crew in the CERN Control Centre extracted the beams from the Large Hadron Collider (LHC), bringing the machine’s first three-year running period to a successful conclusion.

First collisions of pPb run with stable beams
The LHC has just delivered the first pPb (proton-lead) collisions with stable beams of 2013 and CMS is happily running with all sub-detectors on.

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.
