Study of Scaling in the Inclusive Electroproduction Reactionse−+p→e−+π±+X

We report measurements of the inclusive electroproduction reactions $e^{-}+p\to e^{-}+{\pi }^{\pm }+X$. The measurements were made at two data points with the same value of the Bjorken scaling parameter, $\omega =4.1\mathrm{}$, and with $Q^2$ values of 1.20 and 2.02 Ge${\mathrm{V}}^2$. The virtual-photo-production cross sections are studied as a function of missing-mass variables and Feyn-man scaling variables. The results suggest a simple scaling behavior.
