In this note, we present a novel method of extracting the couplings of a new
heavy particle to the Standard Model states. Contrary to the usual discovery
process which involves studying the on-shell production, we look at regions
away from resonance to take advantage of the simple scaling of the
cross-section with the couplings. We apply the procedure to the case of a heavy
quark as an illustration.Comment: 5 pages, 2 figures, Journal accepted versio
