Abstract

A potential model for quark-antiquark states which fits the masses and many of the decay widths of the known mesons is used to predict masses and decay widths of systems including a sixth-flavor quark $t$ as a function of the $t$ -quark mass $m_{t}$ . Linear relations of $t \bar{t}$ and $D_{t}$ and $D_{t}^{*}$ masses as a function of $m_{t}$ are given. Widths for annihilation into $e^{+} e^{-}$ of the vector $t \bar{t}$ states are given. Vector states should be observed with level spacings similar to $ψ$ and $ϒ$ . The lowest of these states should be 1.6-1.7 GeV below $t$ threshold.
