In July of last year we successfully inserted the pixel detector inside CMS and successfully integrated and operated it with the rest of the CMS detector during the CRAFT run. Despite the excellent detector performance some problems arose after…

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.

  Remember the media buzz when we finally pinned down the Higgs boson in 2012? Turns out it might have a shadowy cousin – the dark Higgs – and CMS is chasing it down. CMS scoured its entire Run 2 data set,138 fb–1 of proton-proton collisions at…

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…
