B-hadron production in top quark decay
We present the energy distribution of b-flavoured hadrons in top quark decay using the PYTHIA and HERWIG event generators, which we tune to LEP and SLD data. We find that fitting the string and cluster models is essential to reproduce the ee data and to reliably predict B-hadron production in top decay. We also compare the PYTHIA and HERWIG results with the ones yielded by resummed calculations...
متن کاملQuark Production and Decay †
Direct and indirect information on the top quark mass and its decay modes is reviewed. The theory of top production in hadron-and electron-positron-colliders is presented.
متن کاملHEAVY QUARK PRODUCTION AND DECAY: t, b, AND ONIA
This paper summarizes a variety of recent results on heavy quark production and decay. Considerable progress has been made by CDF and DØ in measuring top quark production and decay properties. The top quark mass been measured with an uncertainty that is less than 3%, a relative precision that is better than has been achieved for other quarks. Measurements of the top production and decay propert...

b-quark decay in the collinear approximation
The semileptonic decay of a b-quark, b → clν, is considered in the relativistic limit where the decay products are approximately collinear. Analytic results for the double differential lepton energy distributions are given for finite charm-quark mass. Their use for the fast simulation of isolated lepton backgrounds from heavy quark decays is discussed.
