B-decay anomalies in Pati–Salam SU(4)
Abstract Attempts to incorporate in a coherent picture the B-decay anomalies presumably observed in $$b\rightarrow c$$ b→c and $$b\rightarrow s$$ b→s semi-leptonic decays have to face the absence of signals in other related experiments, both at low and at high energies. By extending and making more...

| Summary: | Abstract Attempts to incorporate in a coherent picture the B-decay anomalies presumably observed in $$b\rightarrow c$$ b→c and $$b\rightarrow s$$ b→s semi-leptonic decays have to face the absence of signals in other related experiments, both at low and at high energies. By extending and making more precise the content of Barbieri et al. (Eur Phys J C 77(1):8, 2017), we describe one such attempt based on the Pati–Salam SU(4) group, that unifies colour and the B-L charge, in the context of a new strongly interacting sector, equally responsible for producing a pseudo-Goldstone Higgs boson. |
