This thesis presents two analyses of semileptonic b → sl+l-
decays using Flavour Changing Neutral Currents (FCNCs) to test
for the presence of new physics and lepton flavour universality,
and the equality of couplings for different leptons, which on the
basis of experimental evidence is assumed to hold in the Standard
Model, free from uncertainties as a result of knowledge of the
hadronic matrix elements. It also includes the angular analysis
of Lambda_b->Lambda mumu decay and the RK* measurement, both
of which are first measurements, not yet performed by any other
experiment.
