Rebooting the S-matrix bootstrap

06.12.2017 10:00 – 11:00

I will discuss constraints on the S-matrix of gapped, Lorentz invariant quantum field theories due to crossing symmetry, analyticity and unitarity. In particular I will bound cubic couplings, quartic couplings and scattering lengths relevant for the elastic scattering amplitude of two identical scalar particles. After a warm-up in 1+1 dimensions I will move to 3+1 dimensions. In the cases where the results can be compared with results in the older S-matrix literature they are in excellent agreement.
