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.

Unexplained long-range correlations observed in pPb collisions
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.
