Photons from α clustered C+Au collisions at RHIC

Heavy ion collisions at relativistic energies lead to the formation of Quark-Gluon Plasma, a deconfined state of quarks and gluons in local thermal equilibrium. Photons are emitted from each and every stage of the evolving system produced in such collisions and they are considered as one of the most efficient probes to study the initial hot and dense plasma state and its evolution. The results suggest that an experimental determination of photon spectra and anisotropic flow from collisions of carbon with heavy nuclei at relativistic energies may provide valuable information about the exotic α clustered structure of C nucleus. These may also be useful to know more about the initial state as well as photon anisotropic flow produced in relativistic nuclear collisions
