Unified Mueller Picture of Deep-Inelastic Inclusive Leptoproduction

The techniques of Mueller analysis are applied to deep-inelastic processes such as $e^{-}p\to e^{-}\mathrm{hX}$ and $\nu p\to {\mu }^{-}\mathrm{hX}$, where $h$ is a specified hadron and $X$ is unobserved. In the combined Bjorken-Regge limit [$\omega =\left(\frac{2M\nu }{Q^2}\right)$ fixed and large] there are three domains: the target fragmentation region, the central plateau, and the current-fragmentation region. Only the current-fragmentation region provides information not accessible in hadronic collisions. For this region we find an essentially unique Mueller description consistent with assumed Bjorken scaling for inclusive processes. A conclusion of the analyses is that the current-fragmentation region should contain three segments including a plateau of length $\sim \ln \left(\frac{Q^2}{M^2}\right)$. The Mueller description is compared with parton, multiperipheral, and other models.
