abstract

We study the energy or TMD evolution of the three leading twist dipole type T-odd gluon TMDs inside a transversely polarized nucleon, all of which at small $x$ dynamically originate from the spin dependent odderon. Their energy dependence presents a unique opportunity to study the polarization dependent TMD evolution in the small-$x$ region, where the distributions are identical up to a normalization constant at tree level. We further propose to study their evolution via azimuthal asymmetries in virtual photon-jet production in polarized proton-proton collisions at RHIC. We present model predictions for the asymmetries as functions of the large jet or photon transverse momentum and $Q^2$ which set the hard scales in this process.

  1. Single spin asymmetry in forward $pA$ collisions from Pomeron-Odderon interference

    hep-ph 2025-01 conditional novelty 7.0 of 10

    A new Pomeron-Odderon interference term in the hybrid CGC framework yields a percent-level transverse single spin asymmetry in forward pA collisions, with a characteristic sign-changing node at the saturation scale.
