High-Energy Nuon-Proton Scattering: One-Photon Exchange Tests

Abstract

Muon-proton elastic scattering has been studied in the range $0.15<\mathrm{}{q}^2<0.85\mathrm{}$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^2$ with ${\mu }^{+}$ and ${\mu }^{-}$ beams of 6 and 11 GeV/c and a ${\mu }^{-}$ beam of 17 GeV/c. Cross sections have been determined with uncertainties as small as 2%. Rosenbluth straight-line plots and comparisons of the ${\mu }^{+}$ and ${\mu }^{-}$ cross sections show no deviation from the one-photon exchange approximation.
