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…

CMS published its 100th paper on 3rd August. This accomplishment, unprecedented in its pace, came as a result of many things working together extremely well. Primarily, the performance of the LHC accelerator during the last two years was terrific.…

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…

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 unveiling was met with…

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…

This is a collaborative wiki where people write scrappers that can be re-used to trawl the internet or a specific website automatically and find data relating to a particular topic. For instance there is a scrapper that looks through twitter for…
