Quark 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 Gluon Sivers Distribution in D Production at Rhic
The single transverse spin asymmetry in D meson production at RHIC can provide a clean measure of the gluon Sivers distribution function. At intermediate rapidity, D production is largely dominated by the elementary gg → cc̄ channel, where there cannot be any transverse spin transfer. Therefore, any transverse single spin asymmetry observed for D’s produced in pp interactions can only originate ...
متن کاملThe Sivers Function in Constituent Quark Models
A formalism is presented to evaluate the Sivers function in constituent quark models. A nonrelativistic reduction of the scheme is performed and applied to the Isgur-Karl model. The results obtained are consistent with a sizable Sivers effect and the signs for the u and d flavor contributions turn out to be opposite. The Burkardt Sum Rule is fulfilled to a large extent. After the estimate of th...
متن کاملLongitudinal Structure Function at Intermediate x and the Gluon Density
Calculations are presented of the longitudinal structure function FL(x,Q ). We use next-to-leading order expressions in QCD (O(αs)) plus parton densities determined previously from global fits to data on deep inelastic lepton scattering, prompt photon production, and bottom quark production. Anticipated data from the DESY ep collider HERA should provide discriminating information on the gluon d...
