Transverse single-spin asymmetry of midrapidity and mesons in and collisions at

· Physical Review. D.
Presented are the first measurements of the transverse single-spin asymmetries ($$A_N$$) for neutral pions and eta mesons in $$\textit{p}$$ + Au and $$\textit{p}$$ + Al collisions at $$\sqrt{s_{NN}}$$ = 200 GeV in the pseudorapidity range |$$\textit{η}$$| < 0.35 with the PHENIX detector at the Relativistic Heavy Ion Collider. The asymmetries are consistent with zero, similar to those for midrapidity neutral pions and eta mesons produced in $$\textit{p}$$ + $$\textit{p}$$ collisions. These measurements show no evidence of additional effects that could potentially arise from the more complex partonic environment present in proton-nucleus collisions.
