Abstract
Strangeness enhancement has long been considered a signature of quark-gluon plasma formation in heavy-ion collisions. Recently, strangeness enhancement has also been observed in small systems at the Large Hadron Collider (LHC), but the underlying physics is not yet fully understood. This motivates us to study of strange hadron production in small system at Relativistic Heavy Ion Collider (RHIC). In this proceedings, we present new measurements of strange hadrons (KS0, Λ(¯Λ)) in d+Au collisions at √SNN = 200 GeV, collected by the STAR experiment in 2016. We will report pT spectra, dN/dy, <pT>, nuclear modification factor and YAsym of these particles in d+Au collisions.
