High energy polarized $p+p$ collisions at $\sqrt{s}=200-500\,$GeV at the Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) provide a unique way to probe the proton spin structure and dynamics using hard scattering processes. The production of jets and hadrons is the prime focus of gluon polarization studies. The production of $W^{-(+)}$ bosons at...

Accessing the Sivers TMD function in proton+proton collisions through the measurement of transverse single spin asymmetries (TSSAs) in Drell-Yan and weak boson production is an effective path to test the fundamental
QCD prediction of the non-universality of the Sivers function. Furthermore, it provides data to study the spin-flavor structure of valence and sea quarks inside the proton and to...

We summarize the recent results from polarized pp and pA collisions in PHENIX at RHIC. Measurements in high energy longitudinally polarized proton collisions allow us to get access to the contribution of gluon and flavor separated (anti-)quark polarization to the spin of the proton. Measurements with transversely polarized protons help our understanding of parton dynamics within hadrons and...

Mild nuclear effects are predicted for the production cross section and single-spin asymmetry of leading neutrons, in reaction pA=>nX with polarized protons. This result does not contradict the anomalously large asymmetry observed by PHENIX in large rapidity-gap events.

The quantum statistical parton distributions approach proposed more than one decade ago is revisited by considering a larger set of recent and accurate Deep Inelastic Scattering experimental results. It enables us to improve the description of the data by means of a new determination of the parton distributions. This global next-to-leading order QCD analysis leads to a good description of...
