Abstract

Abstract We investigate the RD and

$$ {R}_{D^{\ast }} $$

R D ∗ anomalies in the context of non-minimal SU(5), where Higgs sector is extended by adjoint 45-dimensional multiplet. One of the light spectrum of this model could be the scalar triplet leptoquark that is contained in this multiplet. We demonstrate that this particular scalar leptogquark mediation of the transition b → cτν is capable of simultaneously accounting for both RD and

$$ {R}_{D^{\ast }} $$

R D ∗ anomalies. We further emphasize that another Yukawa coupling controls its contribution to b → sℓ+ℓ−, ensuring that RK and

$$ {R}_{K^{\ast }} $$

R K ∗ remain consistent with the standard model predictions.
