DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/20/">M
 onopole Catalysis From Scattering Amplitudes</a>\nby Ofri Telem (LBNL Phys
 ics Division) as part of NHETC Seminar\n\n\nAbstract\nUsing our novel cons
 truction of the S-matrix for the scattering of electric and magnetic charg
 es\, we address the notoriously confusing effect of Monopole Catalysis. In
  particular\, we provide an on-shell derivation of the Rubakov-Callan effe
 ct\, as well as address the famous “monopole unitarity paradox” - wher
 e there seems to be no valid final state in the scattering of a positron w
 ith a GUT monopole. Our proposed final state involves 3 fermions with tota
 l J=0\, which conserve all SM quantum numbers and can escape the core by v
 irtue of their entanglement with the monopole.\n
