Model independent constraints on leptoquarks from b -> s l+ l- processes    [PDF]

Nejc Kosnik

We list all scalar and vector leptoquark states have effect on the b -> s l+ l- effective Hamiltonian. There are altogether three scalar and four vector leptoquarks that are relevant. For contribution of each state we infer the correlations between effective operators and find that only two baryon number-violating vector leptoquarks give rise to scalar and pseudoscalar operators. We bound contributions of remaining states by imposing experimental constraints coming from Br(B -> K l+ l-), Br(B_s -> mu+ mu-), and the partial branching fraction of B -> X_s mu+ mu-.
