Energy's and amplitudes' positivity
Alberto Nicolis, Riccardo Rattazzi, Enrico Trincherini
In QFT, the null energy condition (NEC) for a classical field configuration is usually associated with that configuration's stability against small perturbations, and with the sub-…
Gauge Boson Mass Generation in AdS4
Riccardo Rattazzi, Michele Redi
We investigate the role of boundary conditions in gauge theories in AdS4. The presence of the boundary can break the gauge symmetry consistently with AdS4 isometries. We show that,…
Theoretical Constraints on the Higgs Effective Couplings
Ian Low, Riccardo Rattazzi, Alessandro Vichi
We derive constraints on the sign of couplings in an effective Higgs Lagrangian using prime principles such as the naturalness principle, global symmetries, and unitarity. Specific…
