Study of the Beam Energy Dependence of Azimuthal Anisotropy Coefficients and Non-Flow Effects in Small System d$+$Au Collisions at RHIC
POSTER
Abstract
Recent measurements of azimuthal anisotropy, v\textunderscore n, in collision systems such as p,d,3He$+$Au suggest that a quark gluon plasma (QGP) may be formed in these small systems, which would be an unexpected discovery. However, this QGP lives for a shorter time than in larger A$+$A systems and it is not clear how the azimuthal anisotropy signals develop. Varying the collision energy in d$+$Au collisions can help to answer this question. However, non-flow effects are more dominant in small systems and must be accounted for in order to draw conclusions. We will show theoretical calculations of v\textunderscore 2 and v\textunderscore 3 in d$+$Au using different models at several collision energies, and we will present a method based on reference fitting to estimate the non-flow component in actual measurements so that they might be better compared to the theory.
