Description
Strangeness production has been suggested as a sensitive probe to the dynamics of the deconfined matter created in heavy-ion collisions. Ratios of particle yields involving strange particles are often utilized to study properties of the nuclear matter at freeze-out, such as the strangeness chemical potential and the chemical freeze-out temperature. The $d$+Au collisions bridge the multiplicity gap between $p$+$p$ and Au+Au collisions and can provide insight to the role of event multiplicity in strange hadron production. The study of strange hadrons in $d$+Au collisions can also help to understand their cold nuclear matter effects, a necessary ingredient for interpreting similar measurements in heavy-ion collisions.
In this poster, we will present new measurements on the production of strange hadrons ($K{_S}{^0}$, $\Lambda$) for different rapidity intervals in $d$+Au collisions at $\sqrt{s_{\rm{NN}}} =$ 200 GeV, recorded by the STAR experiment in 2016. We will report transverse momentum ($p_{\rm{T}}$) spectra, $p_{\rm{T}}$ integrated yield dN/dy, average transverse momentum, yield ratios, nuclear modification factors, and rapidity asymmetry ($Y_{\rm{Asym}}$) for these strange hadrons. The physics implications of these measurements on the collision dynamics will be discussed.
