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

Figure 3

Our theoretical estimates for versus at  GeV and  GeV, for inclusive and production in processes, computed according to (6)–(8) of the text. The contributions from the Sivers and the Collins effects are added together. The computation is performed adopting the Sivers and Collins functions of [20, 22] (SIDIS 1-KRE, left panel) and of [21, 23] (SIDIS 2-DSS, right panel). The overall statistical uncertainty band, also shown, is the envelope of the two independent statistical uncertainty bands obtained following the procedure described in Appendix  A of [21].
