Abstract

Triple differential dijet cross sections in e ^±p interactions are presented in the region of photon virtualities 2 < Q ² < 80GeV ², inelasticities 0.1 < y < 0.85, jet transverse energies E _{T 1}* > 7GeV, E _{T 2}* > 5GeV, and pseudorapidities -2.5 < η ₁*, η ₂* < 0. The measurements are made in the γ* p centre-of-mass frame, using an integrated luminosity of 57 pb ^-1. The data are compared with NLO QCD calculations and LO Monte Carlo programs with and without a resolved virtual photon contribution. NLO QCD calculations fail to describe the region of low Q ² and low jet transverse energies, in contrast to a LO Monte Carlo generator which includes direct and resolved photon interactions with both transversely and longitudinally polarised photons. Initial and final state parton showers are tested as a mechanism for including higher order QCD effects in low E _T jet production.

N2 - Triple differential dijet cross sections in e ±p interactions are presented in the region of photon virtualities 2 < Q 2 < 80GeV 2, inelasticities 0.1 < y < 0.85, jet transverse energies E T 1* > 7GeV, E T 2* > 5GeV, and pseudorapidities -2.5 < η 1*, η 2* < 0. The measurements are made in the γ* p centre-of-mass frame, using an integrated luminosity of 57 pb -1. The data are compared with NLO QCD calculations and LO Monte Carlo programs with and without a resolved virtual photon contribution. NLO QCD calculations fail to describe the region of low Q 2 and low jet transverse energies, in contrast to a LO Monte Carlo generator which includes direct and resolved photon interactions with both transversely and longitudinally polarised photons. Initial and final state parton showers are tested as a mechanism for including higher order QCD effects in low E T jet production.
