Abstract
Two new algorithms for use in the analysis of pp collision are developed to identify the flavour of B[superscript 0] mesons at production using pions and protons from the hadronization process. The algorithms are optimized and calibrated on data, using B[superscript 0]→D[superscript -]π[superscript +] 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. Keywords: Transverse, Momentum, Systematic Uncertainty, Calibration Parameter, Multivariate Classifier, Mistag Probability
