Unitarization of gravity
Iñigo Asiáin, Antonio Dobado, Domènec Espriu
We make use of the improved K-matrix algorithm to obtain unitarized amplitudes in gravity (the so-called Starobisnsky model, of cosmological relevance). The procedure is…

Anomalous Higgs Couplings as a Window to New Physics
I. Asiáin
Throughout this thesis, we investigate how effective field theories, combined with unitarization techniques, can be used to explore physics beyond the Standard Model, with particul…

Accommodating scalar resonances in the HEFT
Iñigo Asiáin, Domènec Espriu, Federico Mescia
Loss of unitarity in an effective field theory is often cured by the appearance of dynamical resonances, revealing the presence of new degrees of freedom. These resonances may mani…
