Description
Transverse Single Spin Asymmetries (TSSAs) in transversely polarized proton-proton collisions ($p^{\uparrow}+p$) have been a fruitful source for studying the spin structure of the proton. In the 2015 RHIC data taking periods, collisions of polarized protons with nuclei ($p^{\uparrow}+A$) were studied for the first time. The measurements of TSSAs in $p^{\uparrow}+p$ and $p^{\uparrow}+A$ collisions can provide a unique opportunity to investigate the origin of TSSA in gluon-rich target nuclei and provide a tool to study nuclear effects in $p+A$ collisions. This presentation will report PHENIX results of TSSAs for charged hadrons ($h^{\pm}$) at forward and backward rapidity ($1.4<|\eta|<2.4$) over the transverse momentum range $1.25
