Isolated photon measurement with the ALICE EMCAL detector

Isolated photons at high transverse momenta are produced in initial hard scattering processes in high energy p-p and heavy ion collisions. Such processes are thought to scale by the number of binary nucleon-nucleon collisions in heavy ion collisions, hence isolated photons can be used to test scaling properties of particle production in such collisions, furthermore they may give insight to possible modifications of nuclear PDFs. In order to interpret isolated photon spectra in heavy-ion and p-Pb collisions at the LHC, they have to be measured in fundamental p-p collisions. This talk focuses on the current status of the isolated photon analysis with the ALICE EMCAL. We discuss technical aspects of the analysis and present methods to define and identify isolated photons. We show first results of the analysis in p-p collisions.
