Invariant Amplitudes for Pion Electroproduction

B. Pasquini, D. Drechsel, L. Tiator

The invariant amplitudes for pion electroproduction on the nucleon are evaluated by dispersion relations at constant t with MAID as input for the imaginary parts of these amplitude…

A dispersive approach to pion photo- and electroproduction

D. Drechsel, B. Pasquini, L. Tiator

The relativistic amplitudes of pion photo- and electroproduction are calculated by dispersion relations at constant t. Several sum rules and low-energy theorems for the threshold a…

The physical meaning of scattering matrix singularities in coupled-channel formalisms

S. Capstick, A. Svarc, L. Tiator +8

The physical meaning of bare and dressed scattering matrix singularities has been investigated. Special attention has been attributed to the role of well known invariance of scatte…

Unitary Isobar Model - MAID2007

D. Drechsel, S. S. Kamalov, L. Tiator

The unitary isobar model MAID2007 has been developed to analyze the world data of pion photo- and electroproduction. The model contains both a common background and several resonan…

Recoil polarization and beam-recoil double polarization measurement of ηelectroproduction on the proton in the region of the S_{11}(1535) resonance

H. Merkel, P. Achenbach, C. A. Ayerbe Gayoso +20

The beam-recoil double polarization P_{x'}^h and P_{z'}^h and the recoil polarization P_{y'} were measured for the first time for the p(\vec{e},e'\vec{p})ηreaction at a four-moment…

Nucleon resonances in πN scattering up to energies \sqrt(s) < 2.0 GeV

Guan Yeu Chen, S. S. Kamalov, Shin Nan Yang +2

A meson-exchange model for pion-nucleon scattering was previously constructed using a three-dimensional reduction scheme of the Bethe-Salpeter equation for a model Lagrangian invol…
