Abstract
We present the model with two light scalar leptoquarks which are able to explain the currently observed deviations from the SM predictions in LFU measurements in B meson decays. The two leptoquarks, \(S_3(\bar{3},3,1/3)\) and \(R_2(3,2,7/6)\), accommodate both \(R_{K^{(*)}}\) and \(R_{D^{(*)}}\) and are in accord with other flavor observables, as well as with Z-pole measurements and direct searches at the LHC. The two LQ states are part of a realistic Grand Unified Theory that remains perturbative to the scale of unification. The predictions of this scenario are enhanced lepton flavor violation signals, \(B \rightarrow K^{(*)}\nu \nu \) decays as well as observable signals in leptoquark production at the LHC.
