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 ...
Angular analysis of the B0 → K*0e+e− decay in the low-q2 region
(Springer, 2015)
An angular analysis of the B0 → K*0e+e− decay is performed using a data sample, corresponding to an integrated luminosity of 3.0 fb−1, collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and ...
Forward production of Υ mesons in pp collisions at √s=7 and 8 TeV
(Springer, 2015)
The production of Υ mesons in pp collisions at √s=7 and 8 TeV is studied with the LHCb detector using data samples corresponding to an integrated luminosity of 1 fb−1 and 2 fb−1 respectively. The production cross-sections ...
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 ...
