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. Due to emission of...

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...

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...

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). CMS observed 10 events containing a distinctive candidate Z boson reconstructed from a pair of electrons...
