New algorithms for identifying the flavour of B⁰mesons using pions and protons: see text] mesons using pions and protons

Two new algorithms for use in the analysis of pp collision are developed to identify the flavour of B⁰mesons at production using pions and protons from the hadronization process. The algorithms are optimized and calibrated on data, using B0→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 B⁰meson is the first of its kind.
