Strange Hadron Production in d+Au Collisions at  \(\sqrt{s_\mathrm{{NN}}} =\) 200 GeV Using the STAR Detector

Strangeness production has been suggested as a sensitive probe to the early dynamics of the deconfined matter created in heavy-ion collisions. Ratios of particle yields involving strange particles are often utilized to study freeze-out properties of the nuclear matter, such as the strangeness chemical potential and the chemical freeze-out temperature. The d+Au collisions connect between Au+Au and p+p collisions, and supply the baseline for the study of strangeness enhancement in the deconfined matter. The study of nuclear modification factors for strange hadrons in d+Au collisions can also help to understand Cronin-like effects. In this work, we will present new measurements on the production of strange hadrons ( \(K_S^0\) , \(\Lambda \) , \(\Xi \) , \(\Omega \) ) for different rapidity intervals in d+Au collisions at \(\sqrt{s_\mathrm{{NN}}} =\) 200 GeV, recorded by the STAR experiment in 2016. We will report transverse momentum ( \(p_\mathrm{{T}}\) ) spectra, \(p_\mathrm{{T}}\) integrated yield (dN/dy), average transverse momentum, yield ratios, nuclear modification factors, and rapidity asymmetry ( \(Y_\mathrm{{asym}}\) ) for those strange hadrons. The physics implications of the measurement on the collision dynamics will be discussed.
