| Description | Speaker: Takemichi Okui Title: Monopole-Fermion Scattering and the Solution to the Semiton/Unitarity Puzzle Room: 3024 Host: John Terning Abstract: The talk will cover my recent work on the so-called semiton/unitarity puzzle in monopole-fermion scattering. Traditionally it was thought such scattering could lead to fractional particle numbers (hence "semitons"), but there are no such states in the Fock space of the theory (hence "unitarity" problem). I will discuss how this problem is solved in Polchinski's "fermion-rotor system", which is an accurate description of charged massless fermions scattering on a magnetic monopole core in the limit of zero gauge coupling. |
