Search for decays of neutral beauty mesons into four muons
A search for the non-resonant decays B 0s → μ + μ − μ + μ − and B 0 → μ + μ − μ + μ − is presented. The measurement is performed using the full Run 1 data set collected in proton-proton collisions by the LHCb experiment ...
Measurement of CP asymmetries in the decays B 0 → K *0 μ + μ − and B + → K + μ + μ −
The direct CP asymmetries of the decays B 0 → K *0 μ + μ − and B + → K + μ + μ − are measured using pp collision data corresponding to an integrated luminosity of 3.0 fb−1 collected with the LHCb detector. The respective ...
Test of lepton universality with B0 → K *0 ℓ + ℓ − decays
A test of lepton universality, performed by measuring the ratio of the branching fractions of the B 0 → K *0 μ + μ − and B 0 → K *0 e + e − decays, RK∗0, is presented. The K *0 meson is reconstructed in the final state K ...
Search for the lepton flavour violating decay τ − → μ − μ + μ −
A search for the lepton flavour violating decay τ − → μ − μ + μ − is performed with the LHCb experiment. The data sample corresponds to an integrated luminosity of 1.0 fb−1 of proton-proton collisions at a centre-of-mass ...
Angular moments of the decay Λ0b → Λμ+μ− at low hadronic recoil
An analysis of the angular distribution of the decay Λ0b → Λμ+μ− is presented, using data collected with the LHCb detector between 2011 and 2016 and corresponding to an integrated luminosity of approximately 5 fb−1. Angular ...
Searches for 25 rare and forbidden decays of D+ and D+s mesons
A search is performed for rare and forbidden charm decays of the form D+(s)→h±ℓ+ℓ(′)∓, where h± is a pion or kaon and ℓ(′)± is an electron or muon. The measurements are performed using proton-proton collision data, ...
