Unitarity Constraints on Anomalous Quartic Couplings
Eduardo da Silva Almeida, O. J. P. Éboli, M. C. Gonzalez-Garcia
We obtain the partial-wave unitarity constraints on the lowest-dimension effective operators which generate anomalous quartic gauge couplings but leave the triple gauge couplings u…

Light-Quark Dipole Operators at LHC
Eduardo da Silva Almeida, N. Rosa Agostinho, Oscar J. P. Éboli +1
We study the effect of operators generating dipole couplings of the light quarks to electroweak gauge bosons on several observables at LHC. We start by demonstrating that the deter…

Electroweak Sector Under Scrutiny: A Combined Analysis of LHC and Electroweak Precision Data
Eduardo da Silva Almeida, Alexandre Alves, N. Rosa Agostinho +2
We perform a comprehensive study of the Higgs couplings, gauge-boson couplings to fermions and triple gauge boson vertices. We work in the framework of effective theories including…
