Abstract A system of dispersive representations of the Omnès–Khuri–Treiman–Sawyer–Wali type for the final-state interactions in the amplitudes of the $$K\rightarrow \pi \pi \pi $$ K → π π π weak transitions is constructed, under the ass

Abstract We continue our study of strongly-coupled, approximately scale-invariant gauge theories with a large number of flavours, which provide a suitable ultraviolet completion of the composite-Higgs scenario. We identify the requisite operators to

Abstract We study strongly-coupled, approximately scale-invariant gauge theories, which develop a mass gap in the infrared. We argue that a large number of fermion flavours is most suitable to provide an ultraviolet completion for the composite Higgs

Abstract Some short-distance properties of the fourth-rank hadronic vacuum polarization tensor are re-examined. Their consequences are critically discussed in the context of the hadronic light-by-light scattering contribution to the anomalous magneti

Abstract The amplitudes for the rare decay modes K ± → π ± ℓ + ℓ − and K S → π 0 ℓ +ℓ− are studied with the aim of obtaining predictions for them, such as to enable the possibility to search for violations of lepton-flavour univer

At order O(αGF), the amplitudes for the decays K→πℓ+ℓ− involve a form factor given by the matrix element of the time-ordered product of the electromagnetic current with the four-quark operators describing weak non-leptonic neutral-current t

Physical Review
Starting from the one-loop divergences we obtained previously, we work out the renormalization of the Higgs-Electroweak Chiral Lagrangian explicitly and in detail. This includes the renormalization of the lowest-order Lagrangian, as well as the decom
