Inclusive electroproduction from protons and deuterons

We present results on the inclusive distributions of final-state hadrons created in deep-inelastic electron scattering from protons and deuterons. Data were taken from all portions of the kinematic range simultaneously in an apparatus which had equal detection efficiency for both charge signs. A subset of the produced hadrons were identified with a threshold-type Čerenkov counter. We find that the charge ratio $\frac{h^{+}}{h^{-}}$ is a strong function of $Q^2$, $x_F$, and ${p_T}^2$, with little dependence on $s$. The ratio of production of $h^{-}$ from deuterium to that from hydrogen as a function of $\phi$ is flat. The invariant cross section for each charge sign and each target exhibits the seagull effect (a correlation in $〈p_T〉$ and $〈x_F〉$). The value of $〈p_T〉$ for data in the range $0.4<\mathrm{}{x}_F<0.85\mathrm{}$ increases slightly as $Q^2$ increases. The exponential dropoff in $p_T$ for production of protons and kaons is similar to that for pions. The dropoff in $x_F$ for production of pions shows a definite dependence on $Q^2$, but this effect is largely caused by the decay products of the exclusive ${\rho }^0$ final state. Finally, $f\left(x_F\right)$ for ${\pi }^{+}$, ${\pi }^{-}$, $K^{+}$, $K^{-}$, $p$, and $\overline{p}$ is presented for each target type.
