The algorithms are optimized and calibrated on data, using {{B} ^0} → D-π + decays from pp collision data collected by LHCb at centre-of-mass energies of 7 and 8 TeV . The tagging power of the new pion algorithm is 60% greater than the previously available one; the algorithm using protons to identify the flavour of a {B} ^0 meson is the first of its kind.15 p.application/pdfengcc-by (c) Camboni, Alessandro et al., 2017https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsinfo:eu-repo/semantics/article6779832022-06-07info:eu-repo/semantics/openAccess
