Sivers function in a spectator model with axial-vector diquarks
We perform a calculation of the Sivers function in a spectator model of the nucleon, with scalar and axial-vector diquarks. We make use of gluon rescattering to produce the nontrivial phases necessary to generate the Sivers function. The inclusion of axial-vector diquarks enables us to obtain a nonzero Sivers function for down quarks. Using the results of our model, we discuss the phenomenology...
متن کاملQuark and Gluon Sivers Functions *
The physics of hadron single transverse spin asymmetries is discussed. Possible measurements of both the quark and gluon Sivers functions are proposed.
متن کاملThe Proton Spin Structure in a Light-cone Quark-spectator-diquark Model
It is shown that the proton spin problem raised by the Ellis-Jaffe sum rule violation does not in conflict with the SU(6) quark model, provided that the relativistic effect from the quark transversal motions, the flavor asymmetry between the u and d valence quarks, and the intrinsic quark-antiquark pairs generated by the nonperturbative meson-baryon fluctuations of the nucleon sea are taken int...
متن کاملGluon plasmon frequency near the light-cone
Thermal perturbation theory based on the resummation scheme by Braaten and Pisarski suffers from unscreened collinear singularities whenever outer momenta become light-like. A recently proposed improvement of the hard thermal loops by an additional resummation of an asymptotic mass promises to solve this problem. Here we present a detailed investigation of the next-to-leading order plasmon self...
