17. Gluon saturation and spin physics: a window into axion-like dynamics

Raju Venugopalan (BNL)

28/01/2021, 13:10

We discuss a novel effective action that captures the interplay of hadron spin and gluon saturation in the Regge limit of QCD . In particular, we discuss an emergent axion like dynamics that is mediated by sphaleron transitions. This indicates a window in the strong interactions with formal connections to axion dynamics in dark matter and radiation, and to the role of sphaleron dynamics in B+L...

20. J/Psi and Psi(2s) production as a probe of low x evolution

Martin Hentschinski (Universidad de las Americas Puebla)

28/01/2021, 13:30

We investigate photo-production of vector mesons J/Psi and Psi(2s), based on both HERA and LHC data, using 2 fits of unintegrated gluon distributions. The latter are subject to non-linear Balitsky-Kovchegov evolution (Kutak-Sapeta gluon; KS) and linear next-to-leading order Balitsky-Kuraev-Fadin-Lipatov evolution (Hentschinski-Sabio Vera-Salas; HSS gluon) respectively. Apart from extending...

21. The impact of gluon saturation in forward dijet/dihadron measurements at the EIC

Farid Salazar (Stony Brook University)

28/01/2021, 13:40

Inclusive measurements of back-to-back dijets/dihadrons in deeply inelastic scattering (DIS) present a promising channel to access signatures of gluon saturation inside nuclear matter at the future Electron Ion Collider (EIC). While most phenomenological studies have been performed within the powerful TMD factorization framework, there are important kinematic (perturbative power) and genuine...

36. Quark and Gluon quasi-PDFs at low-x

Giovanni Antonio Chirilli (University of Regensburg)

Gluon saturation

Quasi parton distribution functions (PDFs) are related to the matrix elements of bilocal operators with space-like separation. The possibility to calculate these objects on the lattice has attracted much attention in the QCD community. I will present the behavior of quark and gluon quasi-PDFs at low-x.
