New single-top production mode discovered

Physics Review Letters just accepted for publication the paper documenting the discovery by CMS (with CP3 contribution) of a new electro-weak process of production of single top quarks in hadron collisions, in which a top quark is accompanied by an on-shell W boson. Read more...

CMS (and CP3) set constraints on the Higgs boson width from off-shell production and decay to ZZ to llll and llvv

The offshell production of the higgs was used to set indirect constraints on the 125GeV higgs boson width. The ZZ->4l and ZZ->2l2v channels were used for this analysis. These important results have been highlighted yesterday as the "hot-topic" of the Morriond EWK conference.

The Physics Department at UCLouvain has been involved for a number of decades in high energy particle physics research, equally strongly on the experimental and instrumental fronts as on the theoretical one. In spite of being located in physically distinct places, all these activities are now brought together within a common organisational structure, the Centre for Cosmology, Particle Physics and Phenomenology (CP3). This structure reinforces the collaboration of these varied components and competences in the physics of the fundamental interactions and the elementary particles.
