invited talk
In this talk we will address new theoretical work on twist-3 spin asymmetries for the process l + N -> h + X, for which nice recent data have been obtained. Specifically, we will discuss the transverse single-spin asymmetry A_N for a polarized nucleon and a polarized final-state hyperon, as well as the longitudinal-transverse double spin asymmetry A_LT. Open questions and future prospects will...

talk
Transverse momentum-dependent parton distributions (TMDs) can be formally defined in terms of hadronic matrix elements of quark bilocal operators containing staple-shaped gauge connections. A parametrization of the matrix elements in terms of invariant amplitudes serves to cast them in the Lorentz frame preferred for a lattice calculation. An ongoing program of evaluating TMD observables...

A dense hadronic system, such as a heavy nucleus or a hadron boosted to high energies, generates strong gluon fields dominated by their classical component. The high density is described by the saturation momentum scale, which provides a dynamical short-distance cutoff and makes these dense systems amenable to perturbative calculations. Building on our previous work, we calculate the...
