Photon reconstruction and identification in heavy ion collisions with the CMS detector

Measurement of isolated photon gives a possibility to constrain the nuclear parton distribution functions (nPDF). The isolated photon is also the clear tag in the photon-jet channel for studying in-medium modifications of fragmentation functions of parton initiated jets. The performance of isolated...

description Measurement of isolated photon gives a possibility to constrain the nuclear parton distribution functions (nPDF). The isolated photon is also the clear tag in the photon-jet channel for studying in-medium modifications of fragmentation functions of parton initiated jets. The performance of isolated photon reconstruction and identification has been studied in PbPb collisions at √SNN = 5.02 TeV. Trigger, reconstruction and isolation efficiencies are measured in PYTHIA+HYDJET Monte-Carlo simulation. We describe signal template method to determine the purity of isolated photons.
