Phenomenological Consequences of Theoretical Constraints on EFTs
Javi Serra (Technical University of Munich)

The unitarity, analyticity and Poincare invariance of a microscopic theory’s S-matrix leaves its imprints at low energies as constraints on the Wilson coefficients of the resulting effective field theory (EFT). In this talk I will discuss the implications of such bounds on various EFTs in particle physics and cosmology, including strongly coupled fermions and vectors, massive gravity, and higher-spin theories.
