Abstract
We have measured muon-proton deep inelastic scattering in the range $0.4<{q}^{2}<3.6$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. The data are consistent with muon-electron universality, and if the ratio $\ensuremath{\rho}=\frac{\ensuremath{\nu}{W}_{2}(\ensuremath{\mu}\ensuremath{-}p)}{\ensuremath{\nu}{W}_{2}(e\ensuremath{-}p)}$ is fitted with the form $\ensuremath{\rho}=N{(1+\frac{{q}^{2}}{{\ensuremath{\Lambda}}^{2}})}^{\ensuremath{-}2}$, we obtain $N=0.997\ifmmode\pm\else\textpm\fi{}0.043$ and ${\ensuremath{\Lambda}}^{\ensuremath{-}2}=+0.006\ifmmode\pm\else\textpm\fi{}0.016$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. This result establishes that $|\ensuremath{\Lambda}|>~5.1$ GeV/c with 95% confidence.
