Meson Exchange Effects in Elastic e-d Scattering

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.

Elastic e-d Scattering Data and the Deuteron Wave Function

What range of momentum components in the deuteron wave function are available ed elastic scattering data sensitive to ? This question is addressed within the context of a model calculation of the deuteron form factors, based on realistic interactions and currents. It is shown that the data on the A(q), B(q), and T20(q) observables at q ≤ 6 fm−1 essentially probe momentum components up to ≃ 4mπ....

Delta-isobar relativistic meson exchange currents in quasielastic electron scattering

We study the role of the ∆-isobar current on the response functions for high energy inclusive quasielastic electron scattering from nuclei. We consider a general Lagrangian which is compatible with contact invariance and perform a fully relativistic calculation in first-order perturbation theory for one-particle emission. The dependence of the responses upon off-shell parametrizations is analyz...

Meson Exchange Currents in Kaon Scattering on the Lightest Nuclei

The K + scattering on the lightest nuclei, d, 3 He and 4 He is studied in the framework of multiple scattering theory. Effects from MEC tied to the K + N → KN π reaction are evaluated. We found that at momentum transfers Q 2 < 0.5 (GeV/c) 2 contributions from MEC are much smaller than kaon rescattering corrections. This makes the conventional multiple scattering picture a reliable tool to study...
