In relativistic nuclear collisions, initial spatial anisotropies subsequently manifest as momentum anisotropies in the final-state particles through the collective expansion of the hot and dense medium produced in such collisions. The presence of alpha clustered structures in light nuclei, such as \(^{7,9}\) Be, \(^{12}\) C, and \(^{16}\) O, induces nuclear deformities, leading to significant spatial anisotropies in the overlap region when collided at relativistic energies. In this work, we investigate the effect of \(\alpha \) clustered structures on the photon anisotropic flow parameters using a hydrodynamical model framework and state of the art photon rates. We observe significant qualitative and quantitative differences between the photon observables from clustered and unclustered cases for 7A TeV \(^{16}\) O+ \(^{16}\) O collisions at the LHC.

摘要

In relativistic nuclear collisions, initial spatial anisotropies subsequently manifest as momentum anisotropies in the final-state particles through the collective expansion of the hot and dense medium produced in such collisions. The presence of alpha clustered structures in light nuclei, such as \(^{7,9}\) Be, \(^{12}\) C, and \(^{16}\) O, induces nuclear deformities, leading to significant spatial anisotropies in the overlap region when collided at relativistic energies. In this work, we investigate the effect of \(\alpha \) clustered structures on the photon anisotropic flow parameters using a hydrodynamical model framework and state of the art photon rates. We observe significant qualitative and quantitative differences between the photon observables from clustered and unclustered cases for 7A TeV \(^{16}\) O+ \(^{16}\) O collisions at the LHC.
