First Measurement of the CP-Violating Phase in B0s→ϕϕ Decays
(American Physical Society, 2013-06-12)
A first flavor-tagged measurement of the time-dependent CP-violating asymmetry in B0s→ϕϕ decays is presented. In this decay channel, the CP-violating weak phase arises due to CP violation in the ...
Measurement of the Semileptonic C P Asymmetry in B0 - ̄B0 Mixing
(American Physical Society, 2015-01-28)
The semileptonic CP asymmetry in B0-¯B0 mixing, adsl, is measured in proton-proton collision data, corresponding to an integrated luminosity of 3.0 fb−1, recorded by the LHCb experiment. Semileptonic ...
Searches for violation of lepton flavour and baryon number in tau lepton decays at LHCb
(Elsevier, 2013-07-09)
Searches for the lepton flavour violating decay $\tau^-\rightarrow \mu^-\mu^+\mu^-$ and the lepton flavour and baryon number violating decays $\tau^-\rightarrow \bar{p}\mu^+\mu^-$ and $\tau^-\rightarrow ...
Isospin Amplitudes in Λ0b→J/ψΛ(Σ0) and Ξ0b→J/ψΞ0(Λ) Decays
(American Physical Society, 2020-02)
Ratios of isospin amplitudes in hadron decays are a useful probe of the interplay between weak and strong interactions and allow searches for physics beyond the standard model. We present the first ...
Measurement of CP asymmetries and polarisation fractions in B0s→K∗0K¯¯¯¯¯∗0 decays
(Springer, 2015-07-30)
An angular analysis of the decay B0s→K∗0K¯¯¯¯¯∗0 is performed using pp collisions corresponding to an integrated luminosity of 1.0 fb−1 collected by the LHCb experiment at a centre-of-mass energy s√=7 ...
Search for the rare decay D0 → μ+μ−
(Elsevier, 2013-08-09)
A search for the rare decay D-0 -> mu(+) mu(-) is performed using a data sample, corresponding to an integrated luminosity of 0.9 fb(-1), of pp collisions collected at a centre-of-mass energy of 7 TeV ...
Measurement of J/ψ polarization in pp collisions at s√=7 TeV
(Springer, 2013-11-09)
An angular analysis of the decay J/ψ→μ + μ − is performed to measure the polarization of prompt J/ψ mesons produced in pp collisions at s√=7 TeV. The dataset corresponds to an integrated luminosity of ...
Effective lifetime measurements in the B0s → K+K− , B0 → K+π− and B0s → π+K− decays
(Elsevier, 2014-09-07)
Measurements of the effective lifetimes in the B0s→K+K−, B0→K+π− and B0s→π+K− decays are presented using 1.0 fb−1 of pp collision data collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. ...
Observation of New Ξ0c Baryons Decaying to Λ+cK−
