Angular analysis of B0→D∗−D∗+s with D∗+s→D+sγ decays
(Springer, 2021)
The first full angular analysis of the B0→D∗−D∗+s decay is performed using 6 fb−1 of pp collision data collected with the LHCb experiment at a centre-of-mass energy of 13 TeV. The D∗+s→D+sγ and D*− → D¯¯¯¯0π− vector meson ...
Measurement of forward Z → e+e− production s√s=8 TeV
(Springer, 2015)
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 ...
Resonances and CP violation in B0s and B¯0s→J/ψK+K− decays in the mass region above the ϕ(1020)
(Springer, 2017)
The decays of B 0s and B¯0s mesons into the J/ψK + K − final state are studied in the K + K − mass region above the ϕ(1020) meson in order to determine the resonant substructure and measure the CP-violating phase, ϕ s , ...
Measurement of the forward W boson cross-section in pp collisions at √s=7 TeV
(Springer, 2014)
A measurement of the inclusive W → μν production cross-section using data from pp collisions at a centre-of-mass energy of √s=7 TeV is presented. The analysis is based on an integrated luminosity of about 1.0 fb−1 recorded ...
Measurement of the CP-violating phase βin B0→J/ψπ+π−decays and limits on penguin effects
(Elsevier, 2015)
Time-dependent CPviolation is measured in the (—)B0→J/ψπ+π−channel for each π+π−resonant final state using data collected with an integrated luminosity of 3.0fb−1in ppcollisions using the LHCb detector. The final state ...
Measurement of the CP-violating phase φsin B0s→J/ψπ+π−decays
(Elsevier, 2014)
The mixing-induced CP-violating phase φsin B0sand B0sdecays is measured using the J/ψπ+π−final state in data, taken from 3fb−1of integrated luminosity, collected with the LHCb detector in 7 and 8TeV centre-of-mass ppcollisions ...
Measurement of the exclusive Υ production cross-section in pp collisions at √s=7 TeV and 8 TeV
(Springer, 2015)
A study is presented of central exclusive production of Υ(nS) states, where the Υ(nS) resonances decay to the μ + μ − final state, using pp collision data recorded by the LHCb experiment. The cross-section is measured in ...
Measurement of CP observables in B± → DK*± decays using two- and four-body D final states
(Springer, 2017)
Measurements of CP observables in B± → DK*± decays are presented, where D denotes a superposition of D0 and D¯0 meson states. Decays of the D meson to K−π+, K−K+, π−π+, K−π+π−π+ and π−π+π−π+ are used and the K*± meson is ...
Measurement of CP violation in B0 → J/ψK 0S and B0 → ψ(2S)K0S decays
(Springer, 2017)
A measurement is presented of decay-time-dependent CP violation in the decays B0 → J/ψ K 0S and B0 → ψ(2S)K 0S, where the J/ψ is reconstructed from two electrons and the ψ(2S) from two muons. The analysis uses a sample of ...
Study of charmonium production in b-hadron decays and first evidence for the decay B0s→ϕϕϕ
(Springer, 2017)
Using decays to φ-meson pairs, the inclusive production
of charmonium states in b-hadron decays is studied
with pp collision data corresponding to an integrated
luminosity of 3.0 fb−1, collected by the LHCb experiment
at ...
