Abstract.We present an overview on the current experimental and phenomenological status of transverse single-spin asymmetries (tSSAs) in proton-proton collisions. In particular, we focus on large-pT inclusive pion, photon, jet, pion-jet production and Drell-Yan processes. For all of them theoretical estimates are given in terms of a generalised parton model (GPM) based on a transverse-momentum-dependent (TMD) factorisation scheme. Comparisons with the corresponding results in a collinear twist-3 formalism and in a modified GPM approach are also made. On the experimental side, a selection of the most interesting and recent results from RHIC is presented.

The Polarized Atomic Hydrogen Jet Target (HJET) Polarimeter commissioned in 2004 was designed to measure absolute polarization of proton beams in Relativistic Heavy Ion Collider (RHIC). HJET performance in RHIC Run 2017 (255 GeV proton beams) will be discussed. The long term (1-100 days) stability of the measured effective analyzing power
