Springer Theses, Recognizing Outstanding Ph.D. Research,2190-50533-319-66422-0 Includes bibliographical references at the end of each chapters.Introduction -- The LHCb Detector at the Large Hadron Collider -- Differential Branching Fraction of Λb0 → Λµ+µ− -- Angular Analysis of Λb0 → Λµ+µ− Decays -- Testing Lepton Favour Universality with RK∗0 -- Conclusions.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.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Elementary particles (Physics)Quantum field theoryMathematical physicsElementary Particles, Quantum Field Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/P23029Theoretical, Mathematical and Computational Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19005Elementary particles (Physics).Quantum field theory.Mathematical physics.Elementary Particles, Quantum Field Theory.Theoretical, Mathematical and Computational Physics.530Pescatore Lucaauthttp://id.loc.gov/vocabulary/relators/aut825016MiAaPQMiAaPQMiAaPQBOOK9910254592903321Searching for New Physics in b → sℓ+ℓ− Transitions at the LHCb Experiment1835137UNINA
