Abstract : This year, LHC provided a very stringent bound on Br(Bs->mu+mu-), bringing it closer to the value predicted by the Standard Model (SM). Bs->mu+mu- was believed to be the golden mode at LHCb to find SUSY because a large enhancement was expected in the regime of moderate and large values of tanb. Other scenarios are still possible and a correlation with other decay channels is needed. We show that a complementary information on New Physics (NP) can be obtained model-indepedently from the B-> K l+l- decay mode. We provide a prediction Br(B-> K l+l-) based on the first lattice QCD results for all three relevant form factors, f0(q^2), f+(q^2) and fT(q^2). We were then able to provide the model-independent bounds on the complex couplings to scalar and pseudoscalr operators in the b->s sector.
