Precise measurement of the b-quark fragmentation function in Z0 boson decays

Abstract
We have developed a new technique for inclusive reconstruction of the energy of B hadrons. The excellent efficiency and resolution of this technique allow us to make the most precise determination of the b-quark fragmentation function, using e+e- -> Z0 decays recorded in the SLD experiment at SLAC. We compared our measurement with the predictions of a number of fragmentation models. We excluded several of these models and measured the average scaled energy of weakly-decaying B hadrons to be =0.714+-0.005(stat)+-0.007(syst) +-0.002(model dependence).
