New CMS Higgs Search Results for the Lepton Photon 2011 Conference
The Higgs boson is the only particle predicted by the Standard Model that has not yet been seen by experiments.

Higgs boson range narrows at European collider
Scientists at the Large Hadron Collider say a signal that suggested they might have seen “hints” of the long-sought Higgs boson particle has weakened.

Should you get excited by your data? Let the Look-Elsewhere Effect decide
A dangerous beast is hiding in today’s searches for the rare signs of new physics — or even “old” physics, such as the Higgs boson — at the Large Hadron Collider.

Measurement of the tt-bar Production Cross Section in pp Collisions at 7 TeV in Lepton + Jets Events Using b-quark Jet Identification
Read the paper: TOP-11-003 The measured production rates of Top-antiTop pairs, where one lepton and four jets of particles is observed in the final state, show good agreement with Quantum Chromodynamics (QCD), the theory of the strong interaction.

How does CMS measure Luminosity?
The number of events that an experiment observes is proportional to a quantity called the luminosity — a measure of how many collisions are occurring in the detector.

HCAL Summer Test Beam Run
This year’s HCAL test beam run in July was completely devoted to studies of hardware that will be used in the upcoming upgrades.

New physics search with same- and opposite-charge di-leptons
High-energy collisions with final states that include leptons (electrons, muons or taus) have played major roles in the history of physics.
