00925njm 22002777a 4500 dc Calvo Gomez, Miriam author Camboni, Alessandro author Vilasis-Cardona, Xavier author LHCb Collaboration - CERN author 2011-11-14 The relative abundance of the three decay modes B0→D−K+, B0→D−π+, and B0s→D−sπ+ produced in 7 TeV pp collisions at the LHC is determined from data corresponding to an integrated luminosity of 35  pb−1. The branching fraction of B0→D−K+ is found to be B(B0→D−K+)=(2.01±0.18stat±0.14syst)×10−4. The ratio of fragmentation fractions fs/fd is determined through the relative abundance of B0s→D−sπ+ to B0→D−K+ and B0→D−π+, leading to fs/fd=0.253±0.017±0.017±0.020, where the uncertainties are statistical, systematic, and theoretical, respectively. http://hdl.handle.net/20.500.14342/3275 https://doi.org/10.1103/PhysRevLett.107.211801 Gran col·lisionador d'hadrons (França i Suïssa) Partícules (Física nuclear) Col·lisions (Física nuclear) Determination of fs/fd for 7 TeV pp Collisions and Measurement of the B0→D−K+ Branching Fraction
