Positron?Lithium Inelastic Scattering with Polarisation Potentials

Photon Polarisation in Diffractive Deep Inelastic Scattering

The distribution of a suitably defined azimuthal angle in diffractive deep inelastic scattering contains information on the polarisation of the exchanged photon. In particular it allows one to constrain the longitudinal diffractive structure function. We investigate the potential of such bounds in general and for particular diffractive final states.

Polarisation potentials for positron-molecule collisions: positron-H, scattering

Model polarisation potentials for use in calculating positron-molecule cross sections are often based on approximations in which terms that depend on the sign of the charge of the projectile are neglected. Thus, these potentials do not fully distinguish between electron and positron scattering. The validity of using such potentials for positronH2 collisions is investigated by performing scatter...

Inelastic Scattering Amplitijdes ”

New results from inelastic two-body scattering reactions are reviewed. Although predictions of SU(3), factorization and simple Regge theory are found to be qualitatively in agreement with the data, direct channel or absorption effects afford the simplest interpretation of the detailed features of the scattering amplitudes.

Deep Inelastic Scattering

Recent deep inelastic results from the H1 collaboration are presented. The topics covered include inclusive diffractive physics, the determination of αS using the event shapes, the study of the hadronic final state at low x with single particles and with jets, the structure function measurements in particular F p 2 at low Q and the high Q physics both in neutral and charged current.
