At the turn of the year, the Tracker management baton passed from GianMario Bilei (picture, at right) to Karl Aaron Gill (picture, at left), who will be the Tracker Project Manager for 2011-2012. GianMario's two-year term started on January 1st,…

The CMS experiment at CERN's Large Hadron Collider (LHC) has completed a search for microscopic black holes produced in high-energy proton-proton collisions. No evidence for their production was found and their production has been excluded up to a…

The 2010 CMS Achievement Awards were given during the opening session of the December CMS Week, on December 6, 2010. Two out of the 14 awardees are Tracker members, whom we warmly congratulate: Gordon Kaussen, for outstanding contributions to the…

After only three weeks of heavy-ion running at CERN’s Large Hadron Collider (LHC), the CMS experiment is already yielding new insights into the condition of matter that existed in the very first instants of the Universe’s life, some 13.7 billion…

The CMS experiment at CERN's Large Hadron Collider (LHC) has recorded its first Lead-Lead collisions at a centre-of-mass energy of 2.76 TeV per nucleon pair, marking the start of its heavy ion research programme. Physicists around the world expect a…

Z bosons produced in collisions of heavy ions have been observed for the first time by the CMS experiment at CERN’s Large Hadron Collider (LHC). CMS observed 10 events containing a distinctive candidate Z boson reconstructed from a pair of electrons…

The CMS Collaboration at CERN released today a paper entitled "Observation of Long-Range Near-Side Angular Correlations in Proton-Proton Collisions" that details signs of a new phenomenon in proton interactions. A study of "high multiplicity"…

For the past four months the LHC has been ramping-up the intensity of the beams, creating billions of 7 TeV proton-proton collisions. This has enabled CMS to study a variety of known physics from the Standard Model, including the "re-discovery" of…

The Tracker held its first "Week" outside CERN. The meeting took place in Hotel Hermitage, a nice seaside resort in the small village of La Biodola on the Elba Island (Italy), from 23 to 28 of May 2010. It was a full-immersion 5-day workshop. The…

The first 7 TeV (3.5 TeV + 3.5 TeV) collisions took place on 30th March 2010, starting around 1pm local (Geneva) time and lasting for about 3.5 hours. Read the CERN Press Release here. The CMS detector and its collaborators are all eagerly awaiting…

After the success of the LHC restart in late 2009, the machine had its first Technical Shutdown over the Christmas period, lasting until the end of February. This time was used fruitfully, both by the accelerator and by CMS (see the first CMS Times…

As the LHC has delivered the first collisions and the first CMS physics paper with collision data is published, in a memorable ceremony Awards for Outstanding Achievements in the Construction of the CMS detector were given to 100 collaborators. 21…
