A Flavorful Composite Higgs Model : Connecting the B anomalies with the hierarchy problem

Abstract

We present a model which connects the neutral current B anomalies with composite Higgs models. The model is based on the minimal fundamental composite Higgs model with $SU(4)/Sp(4)$ coset. The strong dynamics spontaneously break the symmetry and introduce five Nambu-Goldstone bosons. Four of them become the Standard Model Higgs doublet and the last one, corresponding to the broken local $U(1{)}^{\prime }$ symmetry, is eaten by the gauge boson. This leads to an additional TeV-scale $Z^{\prime }$ boson, which can explain the recent B anomalies. The experimental constraints and allowed parameter space are discussed in detail.
