Top Quark Production at the Tevatron: Probing Anomalous Chromomagnetic Moments and Theories of Low Scale Gravity


We review the effects of an anomalous chromomagnetic moment on top quark pair production at the Tevatron for Run II. Apart from an overall rescaling by the total cross section these couplings have little influence on top production characteristics. We then examine how the exchange of a Kaluza-Klein tower of gravitons arising from the low scale quantum gravity scenario of Arkani-Hamed, Dimopoulos and Dvali influences top pair cross sections and several associated kinematical distributions. The data that will be available with Run II luminosities is shown to be sensitive to values of the effective Planck scale of order 1 TeV or more.

The PDF version of this document was distilled from a PostScript file most likely created from LaTeX source which used Type 3 fonts. The resultant PDF may be unreadable on the screen at the default viewing magnification (fonts will appear bitmapped, jagged), though the type will be legible at higher magnifications.

Despite the cosmetic problems resulting from the use Type 3 fonts in the original source file, such PDF files print without problems; likewise, the onscreen text is searchable and selectable.
