DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SymSem/43/">
 Monopoles\, Scattering\, and Generalized Symmetries</a>\nby Marieke van Be
 est (SCGP) as part of Symmetry Seminar\n\n\nAbstract\nI will discuss the p
 roblem of electrically charged\, massless fermions scattering off magnetic
  monopoles. The interpretation of the outgoing states has long been a puzz
 le\, as they can carry fractional quantum numbers. We argue that such outg
 oing particles live in the twisted sector of a topological co-dimension 1 
 surface\, which ends topologically on the monopole. This surface is in gen
 eral noninvertible\, and as such the outgoing radiation not only carries u
 nconventional flavor quantum numbers\, but is trailed by a topological fie
 ld theory\, which is a new prediction.\n
