Elastic meson production and Compton scattering 1
I discuss recent progress in the theory of exclusive meson production and Compton scattering, focusing on hard-scattering factorization and on the dipole formalism.
متن کاملMeson-nucleon Elastic Scattering and Photo-meson Production via the U-channel’
An explanation of the available pion-nucleon and photo-meson production data in the backward direction is proposed using Baryon trajectories. Special emphasis is given to the constraints, the unequal mass kinematics and their implications. I// (Submitted to Phys. Rev. Letters) t Work supported by the U. S.

متن کاملExclusive Vector Meson Production and Deeply Virtual Compton Scattering at HERA ∗
Exclusive vector meson production and deeply virtual Compton scattering are ideally suited reactions for studying the structure of the proton and the transition from soft to hard processes. The main experimental data obtained at HERA are summarised and presented in the light of QCD approaches.
متن کاملCharm Meson Production from Meson-nucleon Scattering
Because of their large masses, one expects charm mesons to be mostly produced in the initial preequilibrium stage of relativistic heavy ion collisions. They have thus been suggested as possible probes of the initial dynamics in these collisions. Previous studies have been concentrated on the production of charm quarks from the preequilibrium partonic matter [1]. For charm meson production from ...
متن کاملElastic Meson Production – Factorisation and Gauge Invariance *
The factorisation of the hard amplitude for exclusive meson production in deep inelastic scattering is considered in the framework of a simple model. It is demonstrated explicitly how gauge invariance ensures the cancellation of non-factorising contributions.
