    The amplitude of the transverse single-spin asymmetry for W± and Z0 boson production measured by STAR in proton-proton collisions

    0

    boson production measured by

    STAR in proton-proton collisions at √

    s = 500 GeV with a recorded luminosity of 25 pb−1

    . The solid gray bands represent

    the uncertainty on the KQ [11] model due to the unknown sea quark Sivers function. The crosshatched region indicates the

    current uncertainty in the theoretical predictions due to TMD evolution
