Baryons in a covariant and confining diquark-quark model
- 1. Institute of Theoretical Physics, Tuebingen (Germany)
Description
In a covariant model where constituent quarks and diquarks interact through quark exchange, the Bethe-Salpeter equation in ladder approximation for octet and decuplet baryons is solved. Quark and diquark confinement is thereby effectively parametrised by choosing appropriately modified propagators. Numerical results for the baryon masses are presented. In a second step electromagnetic, weak and pionic currents are coupled to the bound state according to Mandelstam's technique. The arising matrix elements are evaluated in a generalised impulse approximation and observable form factors are extracted. Copyright (1999) World Scientific Publishing Co. Pte. Ltd
