Abstract

We point out that high-mass thresholds in the evolution of the strong-interaction coupling parameter αs, due to gluinos, squarks and possible new heavy quarks, could introduce appreciable corrections to the transverse momentum dependence of jet production at the Tevatron. If the new thresholds were near scale μ = 200 GeV, thenwithin the limits of asymptotic freedom they could introduce up to 11% increase in αs(μ) (and hence 23% increase in jet production) at scale μ = 500 GeV, compared to Standard Model extrapolations.
