Observation of CP violation in B ± → D K ± decays
(Elsevier, 2012-06-06)
An analysis of B+ to DK+ and B+ to Dpi+ decays is presented where the D meson is reconstructed in the two-body final states: K+pi-, K+K-, pi+pi- and pi+K-. Using 1.0 fb-1 of LHCb data, measurements of ...
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 ...
BCNDataset: Description and Analysis of an Annotated Night Urban Leisure Sound Dataset
(MDPI, 2020-10)
Acoustic pollution has been associated with adverse effects on the health and life expectancy of people, especially when noise exposure happens during the nighttime. With over half of the world population ...
Forward production of Υ mesons in pp collisions at s√=7 and 8 TeV
(Springer, 2015-11-16)
The production of Υ mesons in pp collisions at s√=7 and 8 TeV is studied with the LHCb detector using data samples corresponding to an integrated luminosity of 1 fb−1 and 2 fb−1 respectively. The ...
An FPGA Scalable Software Defined Radio Platform Design for Educational and Research Purposes
(MDPI, 2016-06)
In a digital modem design, the integration of the Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC) with the core processor is usually a major issue for the designer. In this ...
