Effective Field Theory of Gravity to All Orders
Maximilian Ruhdorfer, Javi Serra, Andreas Weiler
We construct the general effective field theory of gravity coupled to the Standard Model of particle physics, which we name GRSMEFT. Our method allows the systematic derivation of…
Hypercharged Naturalness
Javi Serra, Stefan Stelzl, Riccardo Torre +1
We present an exceptional twin-Higgs model with the minimal symmetry structure for an exact implementation of twin parity along with custodial symmetry. Twin particles are mirrors…
Massive Higher Spins: Effective Theory and Consistency
Brando Bellazzini, Francesco Riva, Javi Serra +1
We construct the effective field theory for a single massive higher-spin particle in flat spacetime. Positivity bounds of the S-matrix force the cutoff of the theory to be well bel…
Amplitudes' Positivity, Weak Gravity Conjecture, and Modified Gravity
Brando Bellazzini, Matthew Lewandowski, Javi Serra
We derive new positivity bounds for scattering amplitudes in theories with a massless graviton in the spectrum in four spacetime dimensions, of relevance for the weak gravity conje…
