Model with two scalar leptoquarks: R2 and S3

We discuss a model that can accommodate the B -physics anomalies, based on combining two scalar leptoquarks, R2 and S3, of mass O(1 TeV), and that we proposed in our previous paper. We update the analysis of its parameter space and show that a model remains viable and consistent with a number of low energy and high energy flavor physics constraints. Since the model predicts a nonzero new physics phase, we discuss the possibility to test its contribution to the neutron electric dipole moment and to the angular distributions of the exclusive b -> c tau nu over bar decays. We find that the model can provide a significant enhancement to B(B -> K(*)nu nu) and provides both the upper and lower bounds to B(B -> K(*)mu tau).
