A Study of Anomalous Production of Z-Bosons with High Transverse Momentum at the Tevatron

As part of a broad search for new heavy particles decaying into W and Z bosons, we have measured an upper limit on the anomalous production of Z-bosons with large transverse momentum. The Z bosons, which are produced in $p\bar{p}$ collisions at 1.96 TeV at the Fermilab Tevatron, are studied in the $e^+e^-$ and $\mu^+\mu^-$ final states using the CDF detector. The integrated luminosity of the data samples is 305 $pb^{-1}$. In addition to the comparison with the Standard Model, we have compared the results with the predictions of a specific model, proposed by Bjorken, Pakvasa, and Tuan, of heavy right-handed quarks that decay into the W, Z, and Higgs bosons.
