Beyond Amplitudes' Positivity and the Fate of Massive Gravity
Brando Bellazzini, Francesco Riva, Javi Serra +1
We constrain effective field theories by going beyond the familiar positivity bounds that follow from unitarity, analyticity, and crossing symmetry of the scattering amplitudes. As…
The Other Fermion Compositeness
Brando Bellazzini, Francesco Riva, Javi Serra +1
We discuss the only two viable realizations of fermion compositeness described by a calculable relativistic effective field theory consistent with unitarity, crossing symmetry and…
R-axion at colliders
Brando Bellazzini, Alberto Mariotti, Diego Redigolo +2
We study the effective theory of a generic class of hidden sectors where supersymmetry is broken together with an approximate R-symmetry at low energy. The light spectrum contains…
