Duality in Off-Shell Electromagnetism
In this paper, we examine the Dirac monopole in the framework of Off-Shell Electromagnetism, the five dimensional U(1) gauge theory associated with StueckelbergSchrodinger relativistic quantum theory. After reviewing the Dirac model in four dimensions, we show that the structure of the five dimensional theory prevents a natural generalization of the Dirac monopole, since the theory is not symme...
متن کاملDiscrete Symmetries of Off-Shell Electromagnetism
This paper discusses the discrete symmetries of off-shell electromagnetism, the Stueckelberg-Schrodinger relativistic quantum theory and its associated 5D local gauge theory. Seeking a dynamical description of particle/antiparticle interactions, Stueckelberg developed a covariant mechanics with a monotonically increasing Poincaréinvariant parameter. In Stueckelberg’s framework, worldlines are t...

متن کاملOff-shell String Physics *
Recent advances in non-critical string theory allow a unique continuation, preserving con-formal invariance, of critical Polyakov string amplitudes to off-shell momenta. These continuations possess unusual, apparently stringy, characteristics, which are unlikely to be reproduced in a string field theory. Thus our results may be an indication that some fundamentally new formulation, other than s...
متن کاملConformally Invariant Off - shell Strings ∗
Recent advances in non-critical string theory allow a unique continuation of critical Polyakov string amplitudes to off-shell momenta, while preserving conformal invari-ance. These continuations possess unusual, apparently stringy, characteristics, as we illustrate with our results for three-point functions. 1. The Polyakov functional integral The Polyakov path integral 1 appears only a recipe ...
