Photon Asymmetry

A relativistic plane wave formalism for quasifree eta meson photoproduction is presented. The sensitivity of the unpolarized differential cross section, the recoil nucleon polarization, and the photon asymmetry is investigated. The results indicate that the S11 resonance dominates the unpolarized differential cross section, but that its contribution to the spin observables are very small, for which the D13 resonance plays the primary role.

The differential cross-section data from the CLAS Collaboration for [Formula: see text] have been analyzed based on an effective Lagrangian approach. The [Formula: see text]-channel [Formula: see text], [Formula: see text], [Formula: see text] exchanges, the [Formula: see text]-channel [Formula: see text] and near-threshold [Formula: see text]’s exchanges, the [Formula: see text]-channel [Formula: see text], [Formula: see text], [Formula: see text] exchanges, and the generalized contact term are considered in constructing the reaction amplitude. It is found that by including the [Formula: see text] resonance, which is responsible for the shape of the angular distribution of [Formula: see text] near the [Formula: see text] threshold, and one of the [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] resonances, one can describe the cross-section data for this reaction reasonably well. More experimental data on spin observables are needed to further pin down the resonance contents and associated resonance parameters in this reaction.

Sensitive Testing

It is pointed out that the y-dependence of the differential cross-section for various types of neutrinos on the electron promises to be a sensitive testing ground of the electroweak Standard Model at KAON in Vancouver. Estimates of the flux requirements are given and the feasibility of such experiments is discussed.
