March CERN Courier has a centre spread article on the Tracker with a cover picture.

  CMS observes collective motion of particles in light-ion collisions, providing robust evidence of how initial nuclear geometry maps to final-state flow. For the first time, the CMS experiment has measured how particles flow in collisions of…

CMS sees evidence of the Upsilon meson decaying into two tau leptons for the first time at a hadron collider Beyond our best current understanding of particle physics, encapsulated in the standard model, various theoretical models predict the…
