DESCRIPTION:Speakers: Matthias Neubert (Johannes Gutenberg University\, Ma
 inz)\n\nThe study of color-coherence violation (CCV) in scattering process
 es at hadron colliders has emerged as a fascinating frontier of collider p
 hysics. CCV arises from Glauber-gluon exchange between the initial-state h
 ard partons and leads to a non-universality—that is\, process dependence
 —of spacelike splitting functions\, potentially jeopardizing PDF factori
 zation at high orders in perturbation theory. For LHC jet processes\, we s
 how how perturbative Glauber gluons restore PDF factorization below the je
 t veto scale. At the same time\, Glauber dynamics gives rise to new types 
 of large double-logarithmic corrections\, known as “super-leading” and
  “coherence-violating” logarithms\, as well as to a modified DGLAP evo
 lution at high energies.\n\nhttps://indico.slac.stanford.edu/event/10775/
