High-energy collisions with final states that include leptons (electrons, muons or taus) have played major roles in the history of physics. Several particles – such as J/ψ, W, and Z – as well as productions of pairs of Top quarks were discovered in…

Once more a reminder of the Lepton-Photon approvals, which will start in less than a week from now. The INDICO agenda, now with rooms and EVO booking info, can be found here: https://indico.cern.ch/conferenceDisplay.py?confId=149749 At the top of…

Read the paper: QCD-10-037 This paper extends CMS’s previous measurements of the production rates of isolated prompt photons. The production rates agree with the predictions of perturbative Quantum Chromodynamics (pQCD), although, at low transverse…

Read the paper: QCD-10-037 The measured Drell-Yan production rates, normalised to the production rates in the Z-boson region, show good agreement with the theoretical predictions. The Drell-Yan process occurs when a quark from one of the colliding…

Read the paper: BPH-11-002 The observed numbers of events in both decay modes are consistent with those expected in the Standard Model. Upper limits on the branching fraction have been determined at 90% and 95% confidence levels (CL). The Standard…

A number of EPS talks will be previewed centrally on Tuesday 19 and Wednesday 20 of July. The schedule for these previews can be found on https://indico.cern.ch/conferenceDisplay.py?confId=147431 The room is 40-5-A01 for all previews. The EVO…

The PAS of EXO-10-022 "Search for New Ditau Resonances in pp Collisions at sqrt(s) = 7 TeV" is now public. You find it on CDS at http://cdsweb.cern.ch/record/1367127?ln=en Congratulations to all involved. Best regards, Roberto Tenchini and Gigi…

The PAS of EXO-11-005 "Search for T/t' decays to tZ in pp Collisions at sqrt(s) = 7 TeV" is now public. You can find it on CDS at http://cdsweb.cern.ch/record/1367130?ln=en Congratulations to all involved. Best regards, Roberto Tenchini and Gigi…

The PAS of BTV-11-001 "b-tagging performance (efficiency and mistag rate) measurements from CMS" is now public. You find it on CDS at http://cdsweb.cern.ch/record/1366061?ln=en Congratulations to all involved. Best regards, Roberto Tenchini and Gigi…

We are living in perhaps the most exciting times of the past few decades in High Energy Physics: searching for the Higgs boson, as well as expected and unexpected new physics with one of the most elaborate accelerators ever built, and with complex…

A search for physics beyond the standard model in events with at least three leptons and any number of jets is presented. The data sample corresponds to 35 inverse picobarns of integrated luminosity in pp collisions at sqrt(s) = 7 TeV collected by…

Curious minds might wonder why the LHC, which successfully ran at 7 TeV during the pp run of 2010 began the new year with proton collisions at a significantly less energy of 2.76 TeV. The fact is that this lower energy allowed experiments such as…
