| dc.description | I study the effect of scalar and spin-orbit rescattering terms, in the production of a nonzero Sivers-like asymmetry in proton-proton collisions (nclusive production and Drell-Yan) at moderate center of mass energies $\sqrt{s}$ $<$ 15 GeV and transverse momentum up to 3 GeV/c. An ultrarelativistic generalization of the Glauber formalism is here used to (i) fit the scalar and spin-orbit interaction terms on proton-proton elastic scattering data, including analyzing power, (ii) transfer such information to inclusive proton-proton scattering. It is shown that the phenomenological interactions responsible for the nonzero analyzing power in proton-proton elastic scattering produce a relevant nonzero analyzing power in inclusive processes associated with proton-proton collisions. This could represent a relevant (possibly higher-twist) contribution to the Sivers asymmetry. | |
