Measurement of Dijet Production in Diffractive Deep-Inelastic ep Scattering at HERA
Abstract
A measurement is presented of single- and double-differential dijet cross sections in diffractive deep-inelastic ep scattering at HERA using data collected by the H1 experiment corresponding to an integrated luminosity of 290 pb-1. The investigated phase space is spanned by the photon virtuality in the range of 4<Q2<100 GeV2 and by the fractional proton longitudinal momentum loss xpom<0.03. The resulting cross sections are compared with next-to-leading order QCD predictions based on diffractive parton distribution functions and the value of the strong coupling constant is extracted.
