“…In addition to the rates of semileptonic decays and of neutral B meson oscillations, mentioned above, important constraints can also be obtained from rare B meson decays such as B 0 (s) → µ + µ − [13]. The rare kaon decays, K + → π + νν and K 0 L → π 0 νν, also provide constraints on the apex of the Unitarity Triangle [21,22].…”

Abstract. The phenomenon of CP violation is crucial to understand the asymmetry between matter and antimatter that exists in the Universe. Dramatic experimental progress has been made, in particular in measurements of the behaviour of particles containing the b quark, where CP violation effects are predicted by the KobayashiMaskawa mechanism that is embedded in the Standard Model. The status of these measurements and future prospects for an understanding of CP violation beyond the Standard Model are reviewed.

“…A powerful test of MFV is provided by the study of ratios between b → d and b → s transitions, because their Hamiltonians share the same structure. One particularly important example is the ratio between the decay rates of B 0 and B 0 s into dimuons [33], as this is a purely leptonic decay free from hadronic uncertainties. In the SM such ratios are approximately equal to |V td /V td | ∼ 1/25, only modified by phase space and hadronic matrix elements, while they can take very different values in non-MFV models.…”

Flavour Changing Neutral Currents are transitions between different quarks with the same charge such as b → s processes. These are forbidden at tree level in the Standard Model (SM) but can happen through loop diagrams, which causes the branching ratio of this type of decays to be small, typically ∼ 10 −6 or less. Particles beyond the SM can contribute in the loops enhancing the branching fractions of these decays, which are therefore very sensitive new physics. In this work two analysis of semileptonic b → s + − decays are presented. In the first, Λ

A search for the decay B 0 s → K * 0 µ + µ − is presented using data sets corresponding to 1.0, 2.0 and 1.6 fb −1 of integrated luminosity collected during pp collisions with the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, respectively. An excess is found over the background-only hypothesis with a significance of 3.4 standard deviations. The branching fraction of the B 0 s → K * 0 µ + µ − decay is determined to be The observation of the rare b → d + − FCNC decays B + → π + µ + µ − and Λ 0 b → pπ − µ + µ − has been previously reported by the LHCb collaboration in refs.[9] and [10], respectively. Evidence for the decay B 0 → π + π − µ + µ − has also been established in ref. [11]. The decay B 0 s → K * 0 µ + µ − has not yet been observed. The measured ratio of the B + → π + µ + µ − and B + → K + µ + µ − branching fractions has also been used to determine the ratio of CKM elements |V td /V ts | [12], exploiting correlations between the B → K and B → π form-factors in lattice computations. A similar approach could, in the future, be applied to the ratio of the B 0 s → K * 0 µ + µ − and B 0 → K * 0 µ + µ − decay rates [13]. The decay B 0 → K * 0 µ + µ − , which involves a b → s + − transition, has been studied extensively by BaBar, Belle, CDF and by the LHC experiments [14][15][16][17][18][19]. The rate of the -1 -
