Determination of fs/fd for 7 TeV pp Collisions and Measurement of the B0→D−K+ Branching Fraction
(American Physical Society, 2011-11-14)
The relative abundance of the three decay modes B0→D−K+, B0→D−π+, and B0s→D−sπ+ produced in 7 TeV pp collisions at the LHC is determined from data corresponding to an integrated luminosity of 35 pb−1. ...
Observation of the B0s→η′η′ Decay
(American Physical Society, 2015-07-28)
The first observation of the B0s→η′η′ decay is reported. The study is based on a sample of proton-proton collisions corresponding to 3.0 fb−1 of integrated luminosity collected with the LHCb detector. ...
Measurement of CP Violation in the Phase Space of B±→K±π+π− and B±→K±K+K− Decays
(American Physical Society, 2013-09-03)
The charmless decays B±→K±π+π− and B±→K±K+K− are reconstructed using data, corresponding to an integrated luminosity of 1.0 fb−1, collected by LHCb in 2011. The inclusive charge asymmetries of these ...
Measurement of the branching fraction ratio B(B+c → ψ(2S)π+)/B(B+c → J/ψπ+)
(American Physical Society, 2015-10-20)
Using pp collision data collected by LHCb at center-of-mass energies √s=7 TeV and 8 TeV, corresponding to an integrated luminosity of 3 fb−1, the ratio of the branching fraction of the B+c→ψ(2S)π+ ...

(MDPI, 2015-09)
La Salle and Ebro Observatory have been involved in remote sensing projects in Antarctica for the last 11 years (approximately one solar cycle). The Ebro Observatory has been monitoring and analyzing ...
First evidence for the two-body charmless baryonic decay B0→pp¯¯¯
(Springer, 2013-10-01)
The results of a search for the rare two-body charmless baryonic decays B0→pp¯¯¯ and B0s→pp¯¯¯ are reported. The analysis uses a data sample, corresponding to an integrated luminosity of 0.9 fb−1, of ...

An analysis of the decays of B∓→DK∓ and B∓→Dπ∓ is presented in which the D meson is reconstructed in the three-body final states K∓π±π0, π+π−π0 and K+K−π0. Using data from LHCb corresponding to an ...
Production of J/ψ and Υ mesons in pp collisions at s√=8 TeV
(Springer, 2013-06-14)
The production of J/ψ and Υ mesons in pp collisions at s√=8 TeV is studied with the LHCb detector. The J/ψ and Υ mesons are reconstructed in the μ + μ − decay mode and the signal yields are determined ...
