Role of the Soffer bound in determination of transversity and the tensor charge
Umberto D'Alesio, Carlo Flore, Alexei Prokudin
The transversity and the tensor charge of the nucleon, currently under active investigation experimentally and theoretically, are fundamental quantities in hadron physics as well a…
The gluon Sivers function and its process dependence from RHIC data
Cristian Pisano, Umberto D'Alesio, Carlo Flore +2
We present a phenomenological analysis of available data on single spin asymmetries for pion and meson production in proton-proton collisions at RHIC within the color gauge inv…
Process dependence of the gluon Sivers function in inclusive collisions: theory
Cristian Pisano, Umberto D'Alesio, Carlo Flore +2
Within the color gauge invariant generalized parton model (CGI-GPM), which includes initial and final state interactions in a transverse momentum dependent formalism, we present th…
Process dependence of the gluon Sivers function in inclusive collisions: phenomenology
U. D'Alesio, C. Flore, F. Murgia +2
Within the so-called color gauge invariant generalized parton model, a TMD scheme including initial- (ISI) and final-state (FSI) interactions, we present a phenomenological analysi…
Unraveling the Gluon Sivers Function in Hadronic Collisions at RHIC
Umberto D'Alesio, Carlo Flore, Francesco Murgia +2
We study the transverse single-spin asymmetries for and within the so-called color gauge invariant generalized parton model (CGI-GPM…
