The pionic width of the omega(782) meson within a well-defined, unitary quantum field theory of (anti-)particles and (anti-)holes

We investigate the indirect generation of the partial width of the omega (7 82) meson with respect to the reaction omega (782) --> rho (770)pi --> pi ( +)pi (-)pi (0) within the context of a "Unitary Effective Resonance Model" (UERM), which has previously been applied to resonant fermionic field opera tors, here extended to scalar, pseudoscalar and vector bosonic fields. The omega (782) meson is described by a (quasi-)real field, while the intermedi ate rho (770) meson is considered to be a resonant degree of freedom, which can be treated consistently within the UERM. In the limit of an infinitesimal width (imaginary part of self-energy), the UERM yields a consistent treatment of relativistic quantum field theory (Q FT). Some aspects of the UERM of(anti-)particles and (anti-)holes are discu ssed. (C) 2001 Elsevier Science B.V. All rights reserved.
