アブストラクト:
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.
