The last two weeks the Forward Pixels (FPIX) detectors were both reinstalled and successfully tested. This activity was very much interleaved with the re-alignment of the central beam pipe. Both activities took place in a fragile and confined…

Loic Quertenmont has produced a lot of very nice pictures of events in the 3.8T field. Enjoy the slideshow too...

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

  For the first time, the CMS experiment measures the production of single top quarks in a mode called the “t-channel” at 5.02 TeV, reporting results aligned with the standard model expectations. In the quest to probe the fundamental laws of…

The CMS Collaboration probes decays of the Z boson which would defy our expectations of lepton behavior How strict are Nature's conservation laws governing the interactions among elementary particles? Physicists once assumed, based on experience…

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…
