Nuclear modification factor of isolated prompt photons in pp and PbPb collisions at$\sqrt{s_{NN}}$ =5.02TeV with the CMS detector
High-transverse-momentum prompt photons, as colorless objects, do not interact strongly with the medium and provide a direct way to test perturbative QCD and the nuclear parton distribution functions (nPDFs). The transverse energy spectra and the nuclear modification factors of isolated photons are...
