heal.abstract	Triple differential dijet cross sections in e±p interactions are presented in the region of photon virtualities 2 < Q2 < 80GeV2, inelasticities 0.1 < y < 0.85, jet transverse energies ET 1* > 7GeV, ET 2* > 5GeV, and pseudorapidities -2.5 < η1, η2 < 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 Q2 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 ET jet production. © Springer-Verlag / Società Italiana di Fisica 2004.	en
