The Weak Mixing of Light and Heavy
The source of energy for most of the life on our planet originates from proton-proton collisions at the core of the Sun, which occur at an energy (or temperature) about a billion times less than the collision energy of the LHC.

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 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.

Important heavy-ion results from CMS
The CMS experiment has made several unique measurements using data from LHC collisions of lead nuclei (PbPb, November 2010) at centre-of-mass energies of 2.76 TeV per nucleon pair.

First Z bosons detected by CMS in heavy-ion collisions
Z bosons produced in collisions of heavy ions have been observed for the first time by the CMS experiment at CERN’s Large Hadron Collider (LHC).
