Two new algorithms for use in the analysis of pp collision are developed to identify the flavour of B mesons at production using pions , protons from the hadronization process. The algorithms are optimized , calibrated on data using B-0 -> D- pi(+) decays from pp collision data collected by LIICh at centre -of -mass energies of 7, 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.

Abstract
Two new algorithms for use in the analysis of pp collision are developed to identify the flavour of B mesons at production using pions , protons from the hadronization process. The algorithms are optimized , calibrated on data using B-0 -> D- pi(+) decays from pp collision data collected by LIICh at centre -of -mass energies of 7, 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.File in questo prodotto:
