Mr. Andrea Carlo Marini (ETH Zürich (Switzerland))
We present differential cross-section measurements of inclusive photon production, photon+jet production, and diphoton production in pp collisions based on data recorded by the CMS detector at the LHC. The associated production of a photon and one or more jets in pp collisions provides a direct probe into the hard QCD interaction, is sensitive to gluon densities in the proton, and is a major source of background to standard model searches. The measured distributions are corrected for efficiency and unfolded for detector effects are compared with event generators and theoretical predictions.
