| Abstract: | Two new algorithms for use in the analysis of pp collision are developed to identify the flavour of {B} ^0 mesons at production using pions and protons from the hadronization process. 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. |
