New Physics in Top Sector at the Tevatron
- Yale U.
By now, many thousands of top quarks have been produced at the Fermilab Tevatron Collider. With such high statistics, many precision studies have become possible. In particular, many searches for new physics in the top sector have been performed recently at the CDF and D0 Collaborations. This note will detail some of them, while others will be discussed in a related proceedings note [1]. Most of the analyses we discuss will be directed searches in which a new physics model or class of models is hypothesized, and where the data is analyzed for consistency with the model. We will also discuss one analysis which is simply a study of the top charge directional asymmetry, but which shows an intriguing possible disagreement with Standard Model expectations. Many of these analyses start by reconstructing the top quarks from their decay products, usually after selecting them in the single lepton or the dilepton decay channels. For details on these reconstruction algorithms, please see the proceedings notes on Tevatron top mass measurements [2]. Many of the analyses discussed in these proceedings are in progress and are in the process of adding further data. The reader is advised to consult the public top group webpages for the experiments for the latest results [3].
