High-p_T Particles in the Forward Region at HERA

In order to probe the dynamics of parton evolution in deep inelastic scattering at small x, high-p_T particles produced centrally in pseudorapidity are studied. In the BFKL mechanism gluon radiation is expected to be more abundant than for DGLAP evolution with strong ordering of the gluon transverse momenta, leading to harder p_T spectra. The proposed measurements require charged particle tracking capability as much forward as possible in the HERA laboratory frame, for example with a Very Forward Silicon Tracker, and high luminosity for detailed studies.

A New Method to Probe the low $x$ Parton Dynamics at HERA

Hadron transverse momentum spectra are proposed as a means to probe the underlying partonic dynamics in deep inelastic scattering. The BFKL evolution equation, postulated for small Bjorken-$x$, leads to an enhanced parton emission over the conventional DGLAP ansatz, and can thus be tested.

Hadronic Final States in Deeply Inelastic Scattering

Results on hadronic final states in deeply inelastic scattering are reviewed. They comprise jet production and its interpretation in perturbative QCD, signatures to distinguish conventional QCD dynamics from possible new features of QCD at small $x$, and measurements of inclusive charged particle production. Theoretical developments such as color dipole emission and instanton induced final states are reported on.
