A bstractI 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…

It is shown that, under the requirement of a supersymmetric spectrum with much heavier left-handed doublet superpartners, the assumption favors a considerable enhancement in the tree-level charged-current, while the anomalies induced by the R-parity violating couplings receive up to an approximate 30% improvement.

The phenomenology of this model is considered in the context of the hints for lepton flavor universality violation in semileptonic B decays, and it is found that in b→sℓ^{+}⅓^{-} transitions, the observed deviations from the standard model predictions can be explained with natural values for the free parameters of the model.
