Query: Extracting the Top-Quark Width from Non-Resonant Production   In the context of the Standard Model (SM) of particle physics, the
relationship between the top-quark mass and width ($\Gamma_t$) has been
precisely calculated. However, the uncertainty from current direct measurements
of the width is nearly 50%. A new approach for directly measuring the top-quark
width using events away from the resonance peak is presented. By using an
orthogonal dataset to traditional top-quark width extractions, this new method
may enable significant improvements in the experimental sensitivity in a method
combination. Recasting a recent ATLAS differential cross section measurement,
we find $\Gamma_t$ = 1.28 $\pm$ 0.30 GeV (1.33 $\pm$ 0.29 GeV expected),
providing the most precise direct measurement of the width.
