First Measurement of the CP-Violating Phase in B0s→ϕϕ Decays
(American Physical Society, 2013-06-12)
A first flavor-tagged measurement of the time-dependent CP-violating asymmetry in B0s→ϕϕ decays is presented. In this decay channel, the CP-violating weak phase arises due to CP violation in the ...
Measurement of the ratio of B+c branching fractions to J/ψπ+ and J/ψμ+νμ final states
(American Physical Society, 2014-08-27)
The first measurement that relates semileptonic and hadronic decay rates of the B+c meson is performed using proton-proton collision data corresponding to 1.0 fb−1 of integrated luminosity collected ...
Measurement of the effective B0s → K+K- lifetime
(Elsevier, 2012-10-02)
A precise determination of the effectiveB0s→K+K−lifetime can be used to con-strain contributions from physics beyond the Standard Model in theB0smesonsystem. Conventional approaches selectBmeson ...
Measurement of the cross-section for Z → e+e- production in pp collisions at s√=7 TeV
(Springer, 2013-02-19)
A measurement of the cross-section for pp → Z → e+e− is presented using data at s√=7
TeV corresponding to an integrated luminosity of 0.94 fb−1. The process is measured within the kinematic acceptance ...
Tagged time-dependent angular analysis of B0s→J/ψϕ decays with the 2010 LHCb data
(13th International Conference on B-Physics at Hadron Machines, Amsterdam, 4-8 of April 2011, 2011-04)
The interference between B0s decays to Jψϕ either directly or via B0s−B¯0s oscillation gives rise to a CP violating phase ϕJ/ψϕs. In the Standard Model, this phase is approximately -2βs, where βs = arg ...
Observation of charmonium pairs produced exclusively in pp collisions
(IOPscience, 2014-09)
A search is performed for the central exclusive production of pairs of charmonia produced in proton-proton collisions. Using data corresponding to an
integrated luminosity of 3 fb−1 collected at ...
Measurement of the time-dependent CP asymmetries in B 0s → J/ψK 0S
(Springer, 2015-06-18)
Analisi de l'avaluació incremental i de l'aplicació eficient de l'Algorisme Genètic en un Sistema Classificador
(4rt Congrés Català d'Intel.ligència Artificial, Barcelona, 24-25 d'octubre de 2001, 2001-10)
Aquest article parteix de l'ana!isi del sistema MOLeeS, un sistema classificador (eS) que evoluciona un conjunt de regles de classificació a partir d'algorismes genetics (GA). El sistema es descomposa ...
Impacto de las fuentes externas de conocimiento en la innovación de productos de empresas de baja y media baja intensidad tecnológica
(Universidad ICESI, 2018-12)
A pesar de sus limitaciones, las empresas pequeñas y medianas de baja y media baja intensidad tecnológica se plantean el reto de mejorar su capacidad de innovación. Por esto, se propone un modelo probit ...
Measurement of the B 0 → K ∗0 e + e − branching fraction at low dilepton mass
(Springer, 2013-05-29)
The branching fraction of the rare decay B 0 → K ∗0 e + e − in the dilepton mass region from 30 to 1000 MeV/c 2 has been measured by the LHCb experiment, using pp collision data, corresponding to an ...
