Description

Abstract C++ package BtoVVana is aimed to extract physics parameters in decays of the scalar neutral B-meson to two vector particles in the intermediate state, and two leptons and two pseudoscalar mesons in the final state. An improved angular moments method is implemented in the package BtoVVana: the method uses the time dependent weighting functions and time-integrated observables with variable upper time limit. These observables allow to keep full time informative contents of the decay. By using th... Title of program: BtoVVana Catalogue Id: ADXE_v1_0 Nature of problem The package BtoVVana has been developed to study the performance of the angular moments method of the ΔΓ determination from analysis of untagged decays B 0 s → J/ψ(→ Μ + Μ - )φ(→ K + K - ). By using the package BtoVVana it was shown that the method of angular moments gives stable results and is found to be an efficient and flexible tool for measurements with B 0 s → J/ψφ and B 0 d → J/ψK* decays. Versions of this program held in the CPC repository in Mendeley Data ADXE_v1_0; BtoVVana; 10.1016/j.cpc.2005.11.006 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
