Measurement of the B0s−B¯0s oscillation frequency Δms in B0s→D−s(3)π decays
(Elsevier, 2012-03-19)
The B0s–B0soscillation frequency msis measured with 36 pb−1of data collected inppcollisions at √s=7 TeV by the LHCb experiment at the Large Hadron Collider. A total of 1381B0s→D−sπ+andB0s→D−sπ+π−π+signal ...
Measurements of the branching fractions and CP asymmetries of B± → J/ψ π± and B± → ψ(2S) π± decays
(American Physical Society, 2012-05-07)
A study of B±→J/ψπ± and B±→ψ(2S)π± decays is performed with data corresponding to 0.37 fb−1 of proton-proton collisions at √s=7 TeV. Their branching fractions are found to be B(B±→J/ψπ±)=(3.88±0.11± ...
Comparison of Strategies Based on Evolutionary Computation for the Design of Similarity Functions
(8th International Conference of the ACIA on Artificial Intelligence Research and Development, Alguer, 26-28 October, 2005, 2005-10)
One of the main keys in case-based reasoning system is the retrievalphase, where the most similar cases are retrieved by means of a similarity function.According to the problem, the ...
Dalitz plot analysis of B0 → D¯ 0πþπ− decays
(American Physical Society, 2015-08)
The resonant substructures of B0 → D¯ 0πþπ− decays are studied with the Dalitz plot technique. In this
study a data sample corresponding to an integrated luminosity of 3.0 fb−1 of pp collisions collected ...
Observation of several sources of CP violation in B+ → π+ π+ π− decays
(American Physical Society, 2020-01)
Observations are reported of different sources of CP violation from an amplitude analysis of B+→π+π+π− decays, based on a data sample corresponding to an integrated luminosity of 3 fb−1 of pp collisions ...
Effect of individual cultural attributes on IT professionals' turnover intention
(The Iadis International Conference. Information Systems, Portugal, 18-20 of March 2010, 2010-03)
Employee turnover is one of the major concerns of managers in today’s organizations. Work exhaustion and burnout have
been named among the causes that explain intention to quit and turnover. IT organizations ...
Generació de funcions de similitud mitjançant la Programació Genetica pel Raonament Basat en Casos
(4rt Congrés Català d'Intel.ligència Artificial, Barcelona, 24-25 d'octubre de 2001, 2001-10)
El raonament basat en casos recupera casos utilitzant una funció de similitud. La funció de similitud permet extraure els casos més similars de la memoria de casos al nou cas que volem resoldre. Per ...
