Study of the sign change of the Sivers function from STAR Collaboration W/Z production data

Abstract

Recent data on the transverse single spin asymmetry $A_N$ measured by the STAR Collaboration for $p^{\uparrow }p\to W^{\pm }/Z^{0}X$ reactions at RHIC allow the first investigation of the Sivers function in Drell-Yan processes and of its expected sign change with respect to SIDIS processes. A new extraction of the Sivers functions from the latest SIDIS data is performed and a critical assessment of the significance of the STAR data is attempted.
