Title: General Amplitudes for Beyond the Standard Model Physics
Room: 3024
Host: John Terning
Abstract:
At the LHC and future colliders, in addition to searching for specific
theories, it is crucial to search for new physics model-independently.
In this talk, I will describe how to determine the most general
on-shell scattering interactions involving Standard Model particles
which are SU(3)_c x U(1)_em invariant. By a combination of the
Hilbert series and numerical computations, we have completely
determined the structure for three and four point interactions. One
can then use this classification of the interactions to perform a
systematic search for new physics. As applications, I will discuss
how these enable i) searches for general lepton number violating
decays for the muon and tau and ii) effective field theory searches,
taking into account higher order uncertainties.
