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 ...
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 ...
Measurement of the time-integrated CP asymmetry in D 0 → K 0S K 0S decays
(Springer, 2015)
The time-integrated CP asymmetry in the decay D 0 → K 0S K 0S is measured using 3 fb−1 of proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV. The flavour of the D 0 ...
Measurement of CP asymmetry in B0s → D ∓s K± decays
(Springer, 2014)
We report on measurements of the time-dependent CP violating observables in B 0s → D ∓s K ± decays using a dataset corresponding to 1.0 fb−1 of pp collisions recorded with the LHCb detector. We find the CP violating ...
