Muon Scattering at 219 GeV and the Proton Structure Functions

Abstract

Results on the protron structure function, ${F}_{2}$, are presented for $0.3<{q}^{2}<80.0$ Ge${\mathrm{V}}^{2}$ and $10<\ensuremath{\nu}<200$ GeV. The results support the conclusions of earlier work at 97 and 147 GeV that scaling is violated. A new value for $R=\frac{{\ensuremath{\sigma}}_{S}}{{\ensuremath{\sigma}}_{T}}=0.44\ifmmode\pm\else\textpm\fi{}0.25$ has been obtained using all the Fermilab proton measurements.
