Z{r_arrow}c{bar c}, b{bar b} decays and the aspon model
- Department of Physics and Astronomy, University of Delaware, Newark, Delaware 19716 (United States)
The aspon model predicts mixing of hypothetical new quarks with the standard model quarks. This mixing modifies the decay rates of the Z boson into quarks. In this paper, it is examined whether the measured values of R{sub b}{equivalent_to}{Gamma}(Z{r_arrow}b{bar b})/{Gamma}(Z{r_arrow}hadrons) and R{sub c}{equivalent_to}{Gamma}(Z{r_arrow}c{bar c})/{Gamma}(Z{r_arrow}hadrons) provide any constraints on the aspon model parameters. {copyright} {ital 1998} {ital The American Physical Society}
