Description
Rare decays got recently lots of attention due to the observed anomalies. Of a theoretical point of view these electroweak Penguin diagrams are good know in the Standard Model of particle physics. Since new physics diagrams can change the angular distribution of those decays, the mesurement of those are an important test of the Standard Model of particle physics. For confirming or rejecting the observed tensions, it is from uttermost importance to exploit other b->sl+l- decays.
The angular analysis of one of the baryonic decays, nameliy Λb -> Λ(1520)μ+μ-, is treated in this talk. The analysis is performed within the LHCb experiment.
