Description
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 violation in the early universe.
