Toward a coherent solution of diphoton and flavor anomalies


Buttazzo, Dario; Greljo, Admir; Isidori, Gino; Marzocca, David (2016). Toward a coherent solution of diphoton and flavor anomalies. Journal of High Energy Physics, 2016(8):1-18.

Abstract

We propose a coherent explanation for the 750 GeV diphoton anomaly and the hints of deviations from Lepton Flavor Universality in B decays in terms a new strongly interacting sector with vectorlike confinement. The diphoton excess arises from the decay ofone of the pseudo-Nambu-Goldstone bosons of the new sector, while the flavor anomalies are a manifestation of the exchange of the corresponding vector resonances (with masses in the 1.5-2.5 TeV range). We provide explicit examples (with detailed particle content and group structure) of the new sector, discussing both the low-energy flavor-physics phenomenology and the signatures at high pTT . We show that specific models can provide an excellent fit to all available data. A key feature of all realizations is a sizable broad excess in the tails of τ++ τ−− invariant mass distribution in p p → τ+ +τ−−, that should be accessible at the LHC in the near future.
