High Energy Theory Seminar

I will discuss a computational scheme that allows to construct relativistic scattering
amplitudes that obey analyticity, crossing, elastic and inelastic unitarity in three and four spacetime dimension.
I will present the results of numerical implementation of this scheme. The amplitude functions we
obtain in this way exhibit interesting properties: particle production, Landau curves, nontrivial
Regge limit, logarithmic running. I will comment on the relation to the S-matrix bounds derived by other methods.

In person attendees (469 Lauritsen) must have a valid Caltech ID.
