A Measurement of the b quark fragmentation function at √Q^2=m_Z^0
Abstract
We present a measurement of the b quark fragmentation function D_b(x) from a sample of semi-leptonic B decays collected between 1993 and 1995 at the SLD at SLAC. The energy of each tagged B hadron is reconstructed using missing jet energy, based on the information from the lepton and a partially-reconstructed charm-decay vertex. Account is taken of the effect of primary orbitally excited mesons B^**s). A comparison of the scaled energy distribution with several phenomenological models of heavy quark fragmentation is made, assuming a variety of shapes in the data correction. The average scaled energy is found to be <x_E>=0.699±0.010(stat)±0.019(syst) (Preliminary).
