Transverse Single-Spin Asymmetries in Proton-Proton Collisions at the AFTER@LHC Experiment in a TMD Factorisation Scheme

Figure 10

Our theoretical estimates for in D-Y processes as expected at AFTER@LHC. Our results are presented as function of (upper plots), (middle plots), and of the quark inside the polarised proton, (lower plots). The other kinematical variables are either fixed or integrated, as indicated in each figure. They are computed according to [35] and (21), adopting the Sivers functions of [20] (SIDIS 1, left panels) and of [21] (SIDIS 2, right panels), reversed in sign. The overall statistical uncertainty band, also shown, is obtained following the procedure described in Appendix  A of [21].
