Description
Direct photons produced at early stages of a proton-proton or proton-nucleus collision provide good tool for tuning pQCD predictions,
checking PDF and fragmentation functions. Moreover, direct photon yield in $p$-A collisions can be used as a baseline for thermal direct photon measurements in Pb-Pb collisions.
In this poster, we present the status of analysis of direct photon yield in $p$-Pb collisions at $\sqrt{s_{NN}}=5.02$ TeV measured with
the highly segmented photon spectrometer PHOS of the ALICE experiment.
