摘要:It is well known that one cannot construct a self-consistent quantum field
theory describing the nonrelativistic electromagnetic interaction mediated
by massive photons between a point-like electric charge and a magnetic
monopole. We show that, indeed, this inconsistency arises in the classical
theory itself. No semiclassic approximation or limiting procedure for ℏ→0
is used. As a result, the string attached to the monopole emerges as visible also if finite-range electromagnetic
interactions are considered in classical framework.
