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 ...
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 ...
Observation of B0s –B¯¯¯¯0s mixing and measurement of mixing frequencies using semileptonic B decays
(Springer, 2013-12-04)
The B0s and B 0 mixing frequencies, Δm s and Δm d , are measured using a data sample corresponding to an integrated luminosity of 1.0 fb−1 collected by the LHCb experiment in pp collisions at a centre ...
Concentrated Ground Plane Booster Antenna Technology for Multiband Operation in Handset Devices
(Brno University of Technology, 2014-12)
The current demand in the handset antenna field requires multiband antennas due to the existence of multi-ple communication standards and the emergence of new ones. At the same time, ...
A Methodology to Study the University’s Online Teaching Activity from Virtual Platform Indicators: The Effect of the Covid-19 Pandemic at Universitat Politècnica de Catalunya
(MDPI, 2021-05)
The Covid-19 pandemic led Catalan universities to do all teaching and evaluation onlinefrom 11 March 2020 until the end of term on 30 July. Conventional universities made the transition toonline teaching ...
Observation of a Resonance in B+→K+μ+μ− Decays at Low Recoil
(American Physical Society, 2013-09-10)
A broad peaking structure is observed in the dimuon spectrum of B+→K+μ+μ− decays in the kinematic region where the kaon has a low recoil against the dimuon system. The structure is consistent with ...
Differential branching fraction and angular analysis of the decay B 0 → K ∗0 μ + μ −
(Springer, 2013-08-29)
The angular distribution and differential branching fraction of the decay B 0→ K ∗0 μ + μ − are studied using a data sample, collected by the LHCb experiment in pp collisions at s√=7 TeV, corresponding ...
Model-independent search for CP violation in D0→K-K+π-π+ and D0→π-π+π+π- decays
(Elsevier, 2013-11-04)
A search for CP violation in the phase-space structures of D0 and D0bar decays to the final states K-K+pi-pi+ and pi-pi+pi+pi- is presented. The search is carried out with a data set corresponding to ...
