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

Abstract

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