Data Base

The data base for the reaction p -> K+ contains on the order of 2K data points.

Observables

Observables are defined in terms of both helicity and transversity amplitudes in: Barker, Donnachie and Storrow, Nucl. Phys. B95, 347 (1975). The relation to invariant amplitudes and pole-model resonance couplings is outlined in Adelseck, Bennhold and Wright, Phys. Rev. C32, 1681 (1985).

Multipole Amplitudes

A connection to multipole amplitudes is given in the above ABW reference. At present, the data base is insufficient to support a reliable multipole analysis.
