How does triple-Pomeranchukon coupling modifyF2(ω)?

Abstract

The deep-inelastic electroproduction process is studied in the presence of high-mass diffractive dissociation. The first-order correction, in triple-Pomeranchukon coupling, to the structure function ${F}_{2}(\ensuremath{\omega})$ is explicitly calculated as $\ensuremath{\delta}{F}_{2}(\ensuremath{\omega})=0.013\mathrm{ln}\ensuremath{\omega}$ and $\ensuremath{\delta}{F}_{2}(\ensuremath{\omega})=0.11\ifmmode\times\else\texttimes\fi{}\mathrm{ln}(1+0.11\mathrm{ln}\ensuremath{\omega})$ for large $\ensuremath{\omega}$, corresponding to ${\ensuremath{\alpha}}_{P}^{\ensuremath{'}}=0$ and ${\ensuremath{\alpha}}_{P}^{\ensuremath{'}}=0.25$ Ge${\mathrm{V}}^{\ensuremath{-}2}$, respectively. It is also shown that the diffractive peak of the inclusive cross section for $e(\ensuremath{\mu})+p\ensuremath{\rightarrow}{e}^{\ensuremath{'}}({\ensuremath{\mu}}^{\ensuremath{'}})+{p}^{\ensuremath{'}}+X$ is completely fixed by available parameters from $p+{p}^{\ensuremath{'}}\ensuremath{\rightarrow}{p}^{\ensuremath{'}\ensuremath{'}}+X$ and electroproduction structure functions.
