41. Counting and building operators in theories with hidden symmetries and application to HEFT

Identifying a full basis of operators to a given order is key to the generality of Effective Field Theory (EFT) and is by now a problem of known solution in terms of the Hilbert series. In this talk my primary concerned would be the hidden symmetry in general and Higgs EFT in particular. I will try to make connection between some recent counting formulae in the CCWZ formualtion with the linear...

44. Amplitudes and perturbative unitarity bounds

Luigi Carlo Bresciani (University & INFN Padova)

06/06/2025, 11:50

I will present a formalism based on spinor-helicity techniques that generalizes the formulation of perturbative unitarity bounds. I will discuss unitarity bounds for $N \to M$ scattering processes (with $N,M \ge 2$), which are important for high-energy future colliders. I will also address bounds for spin-2 and higher-spin theories, which are relevant for effective field theories of gravity...
