High Energy Theory Lunchtime Seminar

Friday, November 30th 2018
Speaker: Jaroslav Trnka (UC Davis)
Subject: Effective field theories from soft limits of scattering amplitudes.

In the standard formulation soft limits of scattering amplitudes follow from the symmetries of the QFT. In this talk I will use the opposite approach, and show how a particular set of scalar and vector effective field theories can be fully specified using the constraints on scattering amplitudes. As a result, we rediscover some known effective field theories but also derive new ones.
