Precision measurement of the flavour-changing neutral current transition of a b-quark to an s-quark and two leptons (b->sll) have shown some anomalous results compared to Standard Model predictions over the past decade. These anomalous results have primarily been observed in decays to muons. The existence of a new physics amplitude can cause a sizable interference effect and explain the observed anomalies. However, interference from underestimated hadronic effects also have the potential to explain the anomalies. In this talk, I will introduce the different types of b->sll measurements with a focus on LHCb and how the results indicate the presence of new physics. I will also provide detail on ongoing analyses which aim to measure the new physics couplings while accounting for the interference from hadronic effects.
