Transverse double-spin asymmetries for electroweak gauge-boson production in high-energy polarized p ↑ + p ↑ collisions

Abstract : We consider the production of W and Z/γ * gauge bosons in proton-proton collisions at a center-of-mass energy of √ s = 510GeV available at RHIC at BNL, operating at high luminosity. We stress the importance of measuring the transverse double-spin asymmetries A T T , in connection with available transversely polarized beams with a high degree of polarisation. We will discuss some theoretical issues related to the predicted asymmetries. These studies are contrasted to the 2017 RHIC running operation of transversely polarized beams of mid-rapidity W and Z boson production at a center-of-mass energy of √ s = 510 GeV along with long-term prospects beyond 2020 at RHIC.
