We consider the production and weak decay of a pair of heavy quarks (mesons) ine+e− experiments and study their effect on the various jet distributions. The relative magnitudes of the two-quark-jet and three-quark-jet final states, in the decay of a heavy quark are estimated in the framework of an SU(2)L×U(1) model. We find that the three quark configuration dominates over the two quark configuration. For the quark jets resulting from the weak decay of the heavy quarks, we calculate the jet distributions in Sphericity, Spherocity and Thrust for the process\(e^ +e^ -\to Q\bar Q \to 6\) quarks. These distributions are compared with the corresponding quantities from the non-perturbative process\(e^ +e^ -\to q\bar q\) and the QCD process\(e^ +e^ -\to q\bar qg\). We find that the weak decay of heavy quarks is the dominant mechanism for jet broadening ine+e− experiments, in the intermediate energy region relevant for PETRA and PEP. |
