概要
There is a famous puzzle in QED coupled to N massless Dirac fermions that the scattering of a fermion off a monopole creates an out-state which cannot be any of the elementary particles in the theory. We give a new understanding of the s-wave reduced version of the phenomena by interpreting the magnetic defect as a Tambara-Yamagami line defect.
