Abstract

Upper bounds at the weak scale are obtained for all lambda(ij)lambda(im) type product couplings of the scalar leptoquark model which may affect K-0 - (K) over bar (0), B-d - (B) over bar (d), and B-s - (B) over bar (s) mixing, as well as leptonic and semileptonic K and B decays. Constraints are obtained for both real and imaginary parts of the couplings. We also discuss the role of leptoquarks in explaining the anomalously large CP-violating phase in B-s - (B) over bar (s) mixing.
