Bounding scattering of charged particles in 1+1 dimensions
Abstract We obtain general bounds on scattering processes involving charged particles in 1+1 spacetime dimensions. After a general analysis we derive mostly numerical bounds on couplings in theories with O(N ) and U(N ) global symmetries. The bounds are consistently saturated by S-matrices without p...

| Summary: | Abstract We obtain general bounds on scattering processes involving charged particles in 1+1 spacetime dimensions. After a general analysis we derive mostly numerical bounds on couplings in theories with O(N ) and U(N ) global symmetries. The bounds are consistently saturated by S-matrices without particle production, and in many cases by known integrable S-matrices. Our work provides a blueprint for a similar analysis in higher dimensions. |
