Measurement of D0–¯¯¯D0 Mixing Parameters and Search for CP Violation Using D0→K+π− Decays
(American Physical Society, 2013-12-18)
Measurements of charm mixing parameters from the decay-time-dependent ratio of D0→K+π− to D0→K−π+ rates and the charge-conjugate ratio are reported. The analysis uses data, corresponding to 3 fb−1 of ...
Analyzing technological innovation in low and medium-low tech peruvian manufacturing companies
(Universidad Nacional Autónoma de México, 2019-06)
Greater attention should be given to low- and medium-low- tech companies in emerging countries because they contribute a significant share of GDP and employment in their economies. However, innovation ...
Study of B0s → J/ψπ+π−K+K− decays
(Springer, 2021-02)
The decays B0s → J/ψπ+π−K+K− are studied using a data set corresponding to an integrated luminosity of 9 fb−1, collected with the LHCb detector in proton-proton collisions at centre-of-mass energies of ...
Identification of beauty and charm quark jets at LHCb
(IOPscience, 2015-06)
Identification of jets originating from beauty and charm quarks is important for measuring Standard Model processes and for searching for new physics. The performance of algorithms developed to select ...
Measurement of ψ(2S) production cross-sections in proton-proton collisions at s√=7 and 13 TeV
(Springer, 2020-02)
The cross-sections of ψ(2S) meson production in proton-proton collisions at s√=13 TeV are measured with a data sample collected by the LHCb detector corresponding to an integrated luminosity of 275 pb−1. ...
Hipertextualidad e imitación (A propósito de los "espíritus de amor" en Garcilaso)
(Consejo Superior de Investigaciones Científicas, 2003-06)
La noción de «hipertextualidad» literaria, acuñada por Gerard Genette en su libro Palimpsestes, forma parte de los conceptos teóricos que han caracterizado el paradigma de la teoría literaria ...
Measurement of the B0s→J/ψ¯¯¯¯K*0 branching fraction and angular amplitudes
(American Physical Society, 2012-10-08)
A sample of 114±11 B0s→J/ψK−π+ signal events obtained with 0.37 fb−1 of pp collisions at √s=7 TeV collected by the LHCb experiment is used to measure the branching fraction and polarization amplitudes ...
Observation of the decay B+c → J/ψ K + K − π +
(Springer, 2013-11-12)
The decay B+c → J/ψK + K − π + is observed for the first time, using protonproton collisions collected with the LHCb detector corresponding to an integrated luminosity of 3 fb−1. A signal yield of 78 ± ...
