Description
Nonextensive statistics [1] has attracted attention as a description of an extended range of hadronic particle spectra in nuclear collisions. In this study, we consider a relativistic hydrodynamic model with Tsallis statistics [2] to estimate direct photons, which are a prominent observable for understanding the properties of the QCD matter. Nonextensivity enters the model via the modification of (i) the space-time evolution of the system and (ii) the photon emission rate. Direct photon spectra and elliptic flow are estimated in numerical simulations.
