DESCRIPTION:Speakers: Ignacio Castelli (Temple U)\n\nIn the Standard Model
  of particle physics\, the axial current is not conserved\, due both to fe
 rmion masses and to the axial anomaly.  In the late 1980s it was proposed
  that the axial anomaly could help understand the results of the EMC measu
 rements that led to the nucleon spin crisis.  Recent work has taken a fre
 sh look at the role of the axial anomaly in polarized deep-inelastic scatt
 ering and also extended the discussion to deep-virtual Compton scattering 
 (DVCS).  Important aspects of those works include the apparent connection
  between the U(1) problem and `anomaly poles'\, as well as the dependence 
 of pertinent perturbative results on the infrared regulator.  I will disc
 uss these and related topics\, and our understanding of the current status
  of the field.\n \n\nhttps://indico.bnl.gov/event/33012/
