At 13:25 on Sunday, 13th March, Deputy Run Coordinator, Luca Malgeri told CMS Times: “The current beam is going to be dumped soon, and the next fill is for collisions.”
I am very happy to announce to you all a nice coincidence of events that happened on Friday. During the last one of a long series of approval meetings on 2010 data I have received the news from the P5 crew that CMS was recording the first 2011 collisions.
The CMS Collaboration at CERN released a paper today entitled "First Measurement of W+W− Production and Search for Higgs Boson in pp Collisions at √s = 7 TeV". The paper is the first produced by CMS that includes searches for the Higgs boson at the LHC.
The Compact Muon Solenoid (CMS) Collaboration at CERN’s Large Hadron Collider (LHC) has announced the results of the search for supersymmetry (SUSY) in events with jets and missing transverse energy.
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.
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 years ago.
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.
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.
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.
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.
On 14th December, just 3 weeks after its restart, the LHC collided 1.18TeV beams of protons in CMS for the first time. During this first period more than 15000 2.36 TeV collision events were accumulated by CMS.
On 23rd November the LHC collided 450 GeV beams of protons for the first time (see here) but only for a short period as a trial. The first real period of collisions started on 6th December.
On the weekend of 6th & 7th November the LHC beam was injected and arrived near the CMS experiment, before being "stopped" by a large amount of material known as a "collimator".
