B flavour tagging using charm decays at the LHCb experiment
(IOPscience, 2015-10)
An algorithm is described for tagging the flavour content at production of neutral B
mesons in the LHCb experiment. The algorithm exploits the correlation of the flavour of a B meson
with the charge of ...
Measurement of the ratio of prompt χc to J/ψ production in pp collisions at √s=7TeV
(Elsevier, 2012-12-05)
The prompt production of charmoniumχcandJ/ψstates is studied in proton–proton collisionsat a centre-of-mass energy of√s=7 TeV at the Large Hadron Collider. TheχcandJ/ψmesonsare identified through their ...

Genetic Algorithm Optimization of a High-Directivity Microstrip Patch Antenna Having a Rectangular Profile
(Brno University of Technology, 2013-09)
A single high-directivity microstrip patch antenna (MPA) having a rectangular profile, which can substitute a linear array is proposed. It is designed by using genetic algorithms with the advantage of ...
Measurement of the effective B0s→J/ψK0S lifetime
(Elsevier, 2013-08)
This paper reports the first measurement of the effective B0s→J/ψK0S lifetime and an updated mea-surement of its time-integrated branching fraction. Both measurements are performed with a data sample, ...
Measurement of the polarization amplitudes in B0→J/ψK∗(892)0 decays
(American Physical Society, 2013-09-03)
An analysis of the decay B0→J/ψK∗(892)0 is presented using data, corresponding to an integrated luminosity of 1.0 fb−1, collected in pp collisions at a center-of-mass energy of 7 TeV with the LHCb ...
Nonuniform Overlapping Method in Designing Microstrip Patch Antennas Using Genetic Algorithm Optimization
(Hindawi Publishing Corporation, 2015-01)
Genetic algorithm (GA) has been a popular optimization technique used for performance improvement of microstrip patch
antennas (MPAs).When using GA, the patch geometry is optimized by dividing the patch ...
Search for direct CP violation in D0 → h−h+ modes using semileptonic B decays
(Elsevier, 2013-06-10)
A search for direct CP violation in D0 -> h- h+ (where h=K or pi) is presented using data corresponding to an integrated luminosity of 1.0 fb^-1 collected in 2011 by LHCb in pp collisions at a centre-of-mass ...
Identification and comparison of the main variables affecting early university dropout rates according to knowledge area and institution
(Elsevier, 2023-06-17)
The dropout rate in universities is a widely studied issue that concerns both universities and public organizations. Most studies focus on quantifying the phenomenon and identifying the variables involved. ...
Dalitz plot analysis of B0s→¯D0K−π+ decays
(American Physical Society, 2014-10-14)
The resonant substructure of B0s→¯D0K−π+ decays is studied with the Dalitz plot analysis technique. The study is based on a data sample corresponding to an integrated luminosity of 3.0 fb−1 of pp ...
