Query: Inclusive Two-Jet Production at HERA: Direct and Resolved Cross Sections
  in Next-to-Leading Order QCD   We have calculated inclusive two-jet cross sections in next-to-leading order
QCD for low Q^2 ep collisions superimposing direct and resolved contributions.
Infrared and collinear singularities in the virtual and real contributions are
cancelled with the phase space slicing method. Various inclusive two-jet
distributions have been computed. The results are compared with recent data
from the ZEUS collaboration at HERA.
