R. Aaij, M. Abdelfatah, A.S.W. Abdelmotteleb, C. Abellan Beteta et autres

A measurement of the ratio of semileptonic branching fractions $\mathcal{R}(Jψ)$, defined as $\mathcal{R}(J/ψ) \equiv \mathcal{B}(B_c^+ \to J/ψτ^+ ν_τ)/\mathcal{B}(B_c^+ \to J/ψμ^+ ν_μ)$, is reported using a sample of proton-proton collision data corresponding to an integrated luminosity of 5.4 fb$^{-1}$ recorded by the LHCb …

Measurement of forward Z → e+e− production at s = 8 $$ \sqrt{s}=8 $$ TeV

R. Aaij, B. Adeva, M. Adinolfi, A. A. Affolder et autres

A measurement of the cross-section for Z-boson production in the forward region of pp collisions at 8 TeV centre-of-mass energy is presented.The measurement is based on a sample of Z → e + e -decays reconstructed using the LHCb detector, corresponding to …

Effective lifetime measurements in the Bs0→K+K− , B0→K+π− and Bs0→π+K− decays

R. Aaij, B. Adeva, M. Adinolfi, A. A. Affolder et autres

Measurements of the effective lifetimes in the Bs0→K+K−, B0→K+π− and Bs0→π+K− decays are presented using 1.0fb−1 of pp collision data collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The analysis uses a data-driven approach to correct for the …
