Triangulating an exotic T quark

Abstract

Limits on an exotic heavy quark $T$ are broadly generalized by considering the full range of $T\to Wb,th$ or $tZ$ branching ratios. We combine results of specific $T\to tZ$ and $T\to Wb$ searches with limits on various combinations of decay modes evaluated by re-interpreting other searches. We find strong bounds across the entire space of branching ratios, ranging from $m_T>415$ GeV to $m_T>557$ GeV at 95% confidence level.
