Description
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. $\rm{d}$+Au data connect between Au+Au and $pp$ collisions, and supply the baseline for the study of strangeness enhancement in the deconfined matter. The study of nuclear modification factor in $\rm{d}$+Au collisions can also help to understand Cronin-like effects.
In this work, we will present new measurements on the production of strange hadrons ($K{_S}{^0}$, $\Lambda$, $\Xi$, $\Omega$) at mid-rapidity in $\rm{d}$+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, and nuclear modification factors for those strange hadrons. The physics implications of the measurement on the collision dynamics will be discussed.
