In recent years, significant progress has been made in the development of automated tools that match the parameters of new physics models and the Wilson coefficients of appropriate low-energy Effective Field Theories. This talk will shed light on an extensible, hybrid tool OperatorToC++, that combines the strengths of Mathematica and C++ to facilitate the next steps beyond the matching....
ABC4EFT is a mathematica package aiming to achieve the construction and conversion of operator bases in general effective field theories. The initial release of the package integrated the automatic construction of the physical bases in general Lorentz invariant effective field theories, and now we are going to make a major update to the package to integrate the conversion among different...
With the measurement of double Higgs production within reach, it is justified to expand our interest to more exotic processes, such as three Higgs boson production. This rare process is crucial for advancing our understanding of the Higgs boson, its interactions (including self-coupling), the Higgs potential, and the mechanism of electroweak symmetry breaking (EWSB). This talk explores the...
We analyze causality and unitarity constraints
in graviton scattering amplitudes, aiming to establish new bounds on theories with $U(1)$-gravitational anomalies, such as axion models
or strongly-coupled gauge theories. For this purpose, we show the necessity of coupling these theories to gravity. We obtain a universal scale $\Lambda_{\rm caus}$ at which states with $J\geq 4$ must...
