Search for a vector-like quark with charge 2/3 in t+Z events
Read the paper: EXO-11-005 In this Letter, CMS describes a search for a kind of fourth-generation T quark with charge 2/3. The search for T-antiT pairs was performed in events that had a pair of oppositely charged leptons (l+l−) as well as an additional isolated charged lepton.

Measurement of the t-channel single Top-quark production rates in pp collisions at 7 TeV
The Top quark is the heaviest of the six quarks of the Standard Model and was discovered only 16 years ago by the Tevatron experiments at Fermilab.

Search for Supersymmetry at the LHC in Events with Jets and Missing Transverse Energy
Read the paper: SUS-11-003 The analysis shows no excess of events over the Standard Model expectations.

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.

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.

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.

Measurement of the Differential Cross Section for Isolated Prompt Photon Production in pp Collisions at 7 TeV
Read the paper: QCD-10-037 This paper extends CMS’s previous measurements of the production rates of isolated prompt photons.

Measurement of the Drell–Yan Cross Section in pp Collisions at 7 TeV
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.
