Observed Deviations from Scale Invariance in High-Energy Muon Scattering

Scale noninvariance is observed in 150- and 56-GeV muon scattering from an iron target. In the range 1<q²<40 (GeV/c)², νW₂ rises with q² at fixed ω^'6 and falls at ω^'6. The scale breaking is statistically and systematically significant, and persists with alternative choices of scaling variable. It is parametrized roughly by a constant $b={{{∂}}²ln({ν}×{}{W}₂)}{{∂}ln({{ω}}^{{'}}){∂}ln({q}²}$ with a value near 0.09.
