First measurement of the differential branching fraction and CP asymmetry of the B ± → π ± μ + μ − decay
(Springer, 2015)
The differential branching fraction with respect to the dimuon invariant mass squared, and the CP asymmetry of the B ± → π ± μ + μ − decay are measured for the first time. The CKM matrix elements |V td | and |V ts |, and ...
Differential branching fraction and angular analysis of Λ 0b → Λμ+μ− decays
(Springer, 2015)
The differential branching fraction of the rare decay Λ 0b → Λμ+μ− is measured as a function of q2, the square of the dimuon invariant mass. The analysis is performed using proton-proton collision data, corresponding to ...
Determination of the branching fractions of B0S → D∓S K ∓ and B0 → D −S K +
(Springer, 2015)
Measurements are presented of the branching fractions of the decays B 0S → D ∓S K ∓ and B 0 → D −S K + relative to the decays B 0S → D −S π + and B 0 → D − π +, respectively. The data used correspond to an integrated ...
Differential branching fractions and isospin asymmetries of B → K (*) μ + μ − decays
(Springer, 2014)
The isospin asymmetries of B → Kμ + μ − and B → K * μ + μ − decays and the partial branching fractions of the B 0 → K 0 μ + μ −, B + → K + μ + μ − and B + → K *+ μ + μ − decays are measured as functions of the dimuon mass ...
Measurement of CP violation parameters and polarisation fractions in B0s→J/ψK∗0 decays
(Springer, 2015)
The first measurement of CP asymmetries in the decay B0s→J/ψK∗(892)0 and an updated measurement of its branching fraction and polarisation fractions are presented. The results are obtained using data corresponding to an ...
