Description

Studying transverse single-spin asymmetries (TSSAs) in transversely polarized proton-proton collisions ($p^{\uparrow}+p$) allows us to understand the spin structure of the proton and parton dynamics within the proton. The Relativistic Heavy Ion Collider (RHIC) is a unique apparatus for exploring the nucleon spin structure by colliding polarized protons and protons on ions ($p^{\uparrow}+A$). The measurement of TSSA of light hadrons in polarized pp and polarized pA collision can provide insight into the underlying mechanism of the TSSA. Also, measuring TSSA of open heavy flavor offers a unique opportunity to get information on the trigluon correlation function in the collinear factorization framework.
In this presentation, recent results of TSSAs for positively and negatively charged hadrons at forward and backward rapidity ($1.4<|\eta|<2.4$) over the transverse momentum $1.5
