Test of Lepton Universality Using B+→K+ℓ+ℓ− Decays
(American Physical Society, 2014-10-06)
A measurement of the ratio of the branching fractions of the B+→K+μ+μ− and B+→K+e+e− decays is presented using proton-proton collision data, corresponding to an integrated luminosity of 3.0 fb−1, ...
A study of CP violation in B±→DK± and B±→Dπ± decays with D→K0SK±π∓ final states
(Elsevier, 2014-06-02)
A first study of CP violation in the decay modes B±→[K0SK±π∓]Dh± and B±→[K0SK∓π±]Dh±, where h labels a K or π meson and D labels a D0 or D⎯⎯⎯0 meson, is performed. The analysis uses the LHCb data set ...
