Longitudinal-Transverse Separations of Structure Functions at Low $Q^2$ for Hydrogen and Deuterium

Abstract

We report on a study of the longitudinal to transverse cross section ratio, $R={\sigma }_L/{\sigma }_T$, at low values of $x$ and $Q^2$, as determined from inclusive inelastic electron-hydrogen and electron-deuterium scattering data from Jefferson Lab Hall C spanning the four-momentum transfer range 0.06 $<Q^2<2.8$ GeV${}^2$. Even at the lowest values of $Q^2$, $R$ remains nearly constant and does not disappear with decreasing $Q^2$, as expected. We find a nearly identical behaviour for hydrogen and deuterium.
