Measurement of the CKM angle γ from a combination of LHCb results
(Springer, 2016)
A combination of measurements sensitive to the CKM angle γ from LHCb is performed. The inputs are from analyses of time-integrated B + → DK +, B 0 → DK ∗0, B 0 → DK +π− and B + → DK +π+π− tree-level decays. In addition, ...
Measurements of long-range near-side angular correlations in √sNN=5TeV proton-lead collisions in the forward region
(Elsevier, 2016)
Two-particle angular correlations are studied in proton-lead collisions at a nucleon–nucleon centre-of-mass energy of √sNN=5TeV, collected with the LHCb detector at the LHC. The analysis is based on data recorded in two ...
Measurement of the B0s→J/ψη lifetime
(Elsevier, 2016)
Using a data set corresponding to an integrated luminosity of 3fb−1, collected by the LHCb experiment in ppcollisions at centre-of-mass energies of 7 and 8TeV, the effective lifetime in the B0s→J/ψηdecay mode, τeff, is ...
Measurement of ϒ production in pp collisions at √s=13 TeV
(Springer, 2018)
The production cross-sections of ϒ(1S), ϒ(2S) and ϒ(3S) mesons in proton-proton collisions at √s=13 TeV are measured with a data sample corresponding to an integrated luminosity of 277 ± 11 pb−1 recorded by the LHCb ...
A precise measurement of the B0 meson oscillation frequency
(Springer, 2016)
The oscillation frequency, Δmd, of B0 mesons is measured using semileptonic decays with a D− or D∗− meson in the final state. The data sample corresponds to 3.0fb−1 of pp collisions, collected by the LHCb experiment at ...
Differential branching fractions and isospin asymmetries of B → K (*) μ + μ − decays
(Springer, 2014)
The isospin asymmetries of B → Kμ + μ − and B → K * μ + μ − decays and the partial branching fractions of the B 0 → K 0 μ + μ −, B + → K + μ + μ − and B + → K *+ μ + μ − decays are measured as functions of the dimuon mass ...
Measurement of CP asymmetries in D± → η′π± and D±s → η′π± decays
(Elsevier, 2017)
A search for CPviolation in D±→η π±and D±s→η π±decays is performed using proton–proton collision data, corresponding to an integrated luminosity of 3fb−1, recorded by the LHCb experiment at centre-of-mass energies of ...
Search for CP violation in the phase space of D0→π+π−π+π−decays
(Elsevier, 2017)
A search for time-integrated CPviolation in the Cabibbo-suppressed decay D0→π+π−π+π−is performed using an unbinned, model-independent technique known as the energy test. This is the first application of the energy test in ...
Effective lifetime measurements in the B0s→K+K−, B0→K+π−and B0s→π+K−decays
(Elsevier, 2014)
Measurements of the effective lifetimes in the B0s→K+K−, B0→K+π−and B0s→π+K−decays are presented using 1.0fb−1of ppcollision data collected at a centre-of-mass energy of 7TeV by the LHCb experiment. The analysis uses a ...

(Springer, 2014)
First observations of the rare decays B + → K + π + π − μ + μ − and B +→ ϕK +μ+μ− are presented using data corresponding to an integrated luminosity of 3.0 fb−1, collected by the LHCb experiment at centre-of-mass energies ...
