A critique of the Reggeized Deck model
Edmond L. Berger · University of North Texas Digital Library (University of North Texas) · 1975
A detailed analysis is presented of the Kiggeized pion exchange Deck model for processes of the type ap •* A rl •+ (a ir)N, where a = TT, K, or nudeon and a = p, K , N or A. Predictions of the ncdel for both production and decay properties of the low mass system "k "k A •* (a ir) are derived and contrasted with data.BLffractive as well as charge exchange reactions are treated.The role of pion exchange in generating (a ?) enhancements near threshold and their properties is exanined from several points of view.Characteristic exchange effects and quantum nurber properties (e.g.cross-overs) of the pion exchange Deck graph are sho«n to be verified in the data, but this graph alone is inadequate.The failures all point to the need for a second graph, having a exchange properties.The contributic roughly equal to that of the ir exchange graph."k ie having a exchange properties.The contribution of a exchange is Work performed under the auspices of the U.S. Energy Research and Development Adiinistration.
