La ausencia como categoría teológica. Michel de Certeau, bajo el signo de la ruptura
(Facultat de Teologia de Catalunya, 2013-12)
The historian, anthropologist and sociologist Michel de Certeau (1925-1986) compiled a historiographic map of social practices based on the concept of the “présence manquante”. In this article, the main ...
Measurement of the lifetime of the Bc+ meson using the Bc+→ J/ψπ+ decay mode
(Elsevier, 2015-03-06)
The difference in total widths between the Bc+ and B+mesons is measured using a data sample corresponding to an integrated luminosity of 3.0 fb-1collected by the LHCb experiment in 7 and 8 TeV centre-of-mass ...

Search for the rare decays B0s → μ+ μ− and B0 → μ+ μ-
(Elsevier, 2011-02-14)
A search for the decaysB0s→μ+μ−andB0→μ+μ−is performed with 0.37 fb−1ofppcollisions at√s=7 TeV collected by the LHCb experiment in 2011. The upper limits on the branching fractions areB(B0s→μ+μ−)<1.6×1 ...
Precision Measurement of the Mass and Lifetime of the Ξ0b Baryon
(American Physical Society, 2014-07-15)
Using a proton-proton collision data sample corresponding to an integrated luminosity of 3 fb−1 collected by LHCb at center-of-mass energies of 7 and 8 TeV, about 3800 Ξ0b→Ξ+cπ−, Ξ+c→pK−π+ signal decays ...
Determining Position Inside Non-industrial Buildings Using Ultrasound Transducers
(MDPI, 2007-11)
The position determination inside a building where no GPS signal is beingreceived can be ascertained using laser transmitters in industrial situations where there areno people or using triangulation of ...
Measurement of the ratio of branching fractions B(Bd→K∗0γ)/B(Bs→ϕγ) with the LHCb experiment at s√=7~TeV
(25th International Symposium on Lepton Photon Interactions at High Energies, Mumbai, 22-27 of August 2011, 2011-08)
The ratio of branching ratios of the radiative B decays Bd→K∗0γ and Bs→ϕγ has been measured using 340.1~pb−1 of \emph{pp} collisions at a centre of mass energy of s√=7~TeV taken with the LHCb detector. ...
An Approach to Frequency Selectivity in an Urban Environment by Means of Multi-Path Acoustic Channel Analysis
(MDPI, 2019-06)
The improvement of quality of life in the framework of the smart city paradigm cannot be limited to a set of objective measures carried out over several critical parameters (e.g., noise or air pollution). ...
First observation of the decay B+→π+μ+μ−
(Springer, 2012-12-21)
A discovery of the rare decay B + → π + μ + μ − is presented. This decay is observed for the first time, with 5.2 σ significance. The observation is made using pp collision data, corresponding to an ...
