CERN Accelerating science

Once more a reminder of the Lepton-Photon approvals, which will start in less than a week from now.

CERN, focus of research into the Big Bang and what makes the universe tick, on Thursday announced a new program -- fusing science with art to encourage painting and music inspired by the wonders of the cosmos.

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 energies, the predictions tend to be higher than the measured values.

The current data from the LHC show an effect which might, or might not, be the first indication of the presence of a Higgs boson. Most of this effect is due to the number of pairs of W bosons which are being produced in proton-proton collisions.

This is a well-written piece exploring the need for more data and what possible interpretations there could be: http://www.guardian.co.uk/science/life-and-physics/2011/aug/06/1

Building 40 at CERN’s Meyrin site was abuzz with excitement as CMS formally inaugurated an art installation featuring a full-size high-resolution photograph of the CMS detector organised by the CMS Communications Group.

The measured Drell-Yan production rates, normalised to the production rates in the Z-boson region, show good agreement with the theoretical predictions.

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 CMS collaboration is presenting its latest results this week at the 2011 Europhysics Conference on High-Energy Physics, held in Grenoble, France.
