Abstract:

Three-jet events produced by e+e- annihilation into hadrons at 34.6 GeV c.m. energy were studied by comparing them with 2nd order QCD and two different models of fragmentation. The distribution of low energy particles in the 3-jet plane is found to be better described by the LUND color string model than by the independent jet model. The opposite is true for more energetic particles flowing between the 3 jets. The average transverse momenta in jets can be described with values of σq between 350 and 500 MeV/c for the gluon jet. © 1985 Springer-Verlag.

Abstract:

We have determined the average lifetime of hadrons containing b quarks produced in e+e- annihilation to be τB = 1.83 +0.83 +0.37 - -0.34×10-12s. Our method uses charged decay products from both non-leptonic and semileptonic decay modes. © 1984.
