Measurement of the charge asymmetry in B±→ϕK±B±→ϕK± and search for B±→ϕπ±B±→ϕπ± decays
(Elsevier, 2014-01-20)
The CP-violating charge asymmetry in B±→ϕK±B±→ϕK± decays is measured in a sample of pp collisions at 7 TeV centre-of-mass energy, corresponding to an integrated luminosity of 1.0 fb−1 collected by the ...
Observation of a New Excited D+s Meson in B0→D−D+K+π− Decays
(American Physical Society, 2021-03)
Using pp collision data corresponding to an integrated luminosity of 5.4 fb−1 collected with the LHCb detector at a center-of-mass energy of 13 TeV, the B0→D−D+K+π− decay is studied. A new excited D+s ...
Differential branching fraction and angular analysis of Λ 0 b → Λμ+μ− decays
(Springer, 2015-06-17)
The differential branching fraction of the rare decay Λ 0 b → Λμ+μ− is measured as a function of q2, the square of the dimuon invariant mass. The analysis is performed using proton-proton collision ...
