First evidence of direct CP violation in charmless two-body decays of B0s mesons
(American Physical Society, 2012-05-16)
Using a data sample corresponding to an integrated luminosity of 0.35 fb−1 collected by LHCb in 2011, we report the first evidence of CP violation in the decays of B0s mesons to K±π∓ pairs, ...
Measurement of forward J/ψ production cross-sections in pp collisions at s√=13 TeV
(Springer, 2015-10-26)
The production of J/ψ mesons in proton-proton collisions at a centre-of-mass energy of s√=13 TeV is studied with the LHCb detector. Cross-section measurements are performed as a function of the transverse ...
Sensing System for Remote Areas in Antarctica
(Wiley, 2020-02)
Every year, the number of Internet of Things devices is growing exponentially. The current Internet of Things technology to support the connectivity of such a huge number of devices is limited by the ...
Educating urban designers using augmented reality and mobile learning technologies
(Asociación Iberoamericana de Educación Superior a Distancia : Universidad Nacional de Educación a Distancia, 2017-01-07)
This paper describes an educational experience using augmented reality (AR) on mobile devices as a tool for learning urban design concepts and specifically for architecture degree students. ...
First measurement of time-dependent CP violation in B0s→K+K− decays
(Springer, 2013-10-25)
Direct and mixing-induced CP-violating asymmetries in B0s→K+K− decays are measured for the first time using a data sample of pp collisions, corresponding to an integrated luminosity of 1.0 fb−1, collected ...
Search for the Λ 0b → Λη ′ and Λ 0b → Λη decays with the LHCb detector
(Springer, 2015-09-01)
A search is performed for the as yet unobserved baryonic Λ 0b → Λη ′ and Λ 0b → Λη decays with 3 fb−1 of proton-proton collision data recorded by the LHCb experiment. The B0 → K 0s η ′ decay is used ...
Measurement of the Z+b-jet cross-section in pp collisions at s√ = 7 TeV in the forward region
(Springer, 2015-01-13)
The associated production of a Z boson or an off-shell photon γ * with a bottom quark in the forward region is studied using proton-proton collisions at a centre-of-mass energy of 7 TeV. The Z bosons ...
Measurement of b-hadron branching fractions fortwo-body decays into charmless charged hadrons
(Springer, 2012-10-04)
Based on data corresponding to an integrated luminosity of 0.37 fb−1 collected by the LHCb experiment in 2011, the following ratios of branching fractions are measured:
$
B(B0→π+π−)/B(B0→K+π−)=0.262±0 ...
Measurement of b hadron production fractions in 7 TeV pp collisions
(American Physical Society, 2012-02-24)
Measurements of b hadron production ratios in proton-proton collisions at a center-of-mass energy of 7 TeV with an integrated luminosity of 3 pb−1 are presented. We study the ratios of strange B meson ...
Search for the lepton flavour violating decay τ − → μ − μ + μ −
(Springer, 2015-02-18)
A search for the lepton flavour violating decay τ − → μ − μ + μ − is performed with the LHCb experiment. The data sample corresponds to an integrated luminosity of 1.0 fb−1 of proton-proton collisions ...
