Polarized proton-proton collisions have opened the door to new transverse spin phenomena that are not accessible in SIDIS.
Among them are questions of universality and factorization, which lie at the center of our interpretation of experimental data.
This talk will highlight recent results in transverse spin physics in p+p at RHIC and discuss opportunities with polarized proton collisions...

Single Spin Asymmetries in hard collision processes are associated with non-perturbative QCD dynamics leading to spin-directed momentum transfers. These non-perturbative spin-directed momentum transfers can occur either in an initial state or in the fragmentation leading to a final state particle. The dynamical mechanisms leading to single-spin asymmetries are parameterized either as...

We study how the rapidity evolution of gluon transverse momentum dependent distribution changes from small x ≪ 1 to moderate x ∼ 1.

In the framework of Schwinger-Dyson Equations, we calculate the (neutral) Pion-to-two-photons transition form factor. This problem involves quantitatively careful parameterization of the quark propagator and the pion Bethe-Salpeter amplitudes in order to be able to numerically access large space-like momenta of the probing photons. Also, in order to be consistent with the so-called chiral...
