Addressing the B-physics anomalies in a fundamental Composite Higgs model

Abstract

Abstract I present a model addressing coherently the naturalness problem of the electroweak scale and the observed pattern of deviations from the Standard Model in semileptonic decays of B mesons. The Higgs and the two scalar leptoquarks responsible for the B-physics anomalies, S1=3¯,1,1/3 $$ {S}_1=\left(\overline{\mathbf{3}},\mathbf{1},1/3\right) $$ and S3=3¯,3,1/3 $$ {S}_3=\left(\overline{\mathbf{3}},\mathbf{3},1/3\right) $$, arise as pseudo Nambu-Goldstone bosons of a new strongly coupled sector at the multi-TeV scale. I focus on an explicit realization of such a dynamics in terms of a new strongly coupled gauge interaction and extra vectorlike fermions charged under it. The model presents a very rich phenomenology, ranging from flavour observables, Higgs and electroweak precision measurements, and direct searches of new states at the LHC.
