HERA, the first electron-proton collider, has been delivering luminosity since 1992. It is the natural extension of an impressive series of fixed-target leptonnucleon scattering experiments. The increase of a factor ten in center-of-mass energy over that available for fixed-target experiments has allowed the discovery of several important results, such as the large number of slow partons in the proton, and the sizeable diffractive cross section at large Q 2 . Recent data point to a possible deviation from Standard Model expectations at very high Q 2 , highlighting the physics potential of HERA for new effects. The HERA program is currently in a transition period. The first six years of data taking have primarily elucidated the structure of the proton, allowed detailed QCD studies and had a strong impact on the understanding of QCD dynamics. The coming years will bring the era of electroweak studies and high Q 2 measurements. This is therefore an appropriate juncture at which to review HERA results.

Jet cross sections in deeply inelastic scattering in the case of transverse photon exchange for the production of (1+1) and (2+1) jets are calculated in next-to-leading order QCD (here the '+1' stands for the target remnant jet, which is included in the jet definition for reasons that will become clear in the main text). The jet definition scheme is based on a modified JADE cluster algorithm. The calculation of the (2+1) jet cross section is described in detail. Results for the virtual corrections as well as for the real initial-and final state corrections are given explicitly. Numerical results are stated for jet cross sections as well as for the ratio σ (2+1) jet /σ tot that can be expected at E665 and HERA. Furthermore the scale ambiguity of the calculated jet cross sections is studied and different parton density parametrizations are compared.

“…• DISJET [18]: Again the jet definition is restricted to the modified JADE scheme; the program is based on the calculation in Refs. [19,20]. • MEPJET [21]: This is a program for the calculation of arbitrary observables which uses the phase-space-slicing method.…”

I review the status of next-to-leading-order calculations for hadronic final states in deeply-inelastic lepton-nucleon scattering. In more detail, I focus on calculations of (2+1)-jet-type cross sections, describe recent progress in extending the perturbative description into the transition region between deeply inelastic scattering and photoproduction, and study the validity of the fragmentation function picture for one-particle-inclusive cross sections at small Q 2 and small xp. ‡ Electronic mail address: Dirk.Graudenz@psi.ch,
