Determination of event shape distributions and αsb from events at LEP
Abstract
In hadronic Z0 decays collected by the OPAL experiment at LEP, event shape variables such as jet rates, jet masses, thrust and the energy-energy correlation for$$Z^0 \to b\bar b$$ events are compared to those for all flavours using secondary vertex information to tag the b quarks. The measured distributions are found to be well described by anO"(αs) calculation for heavy quarks as well as by parton shower simulations. We also determine the …
