dc.descriptionWe investigate the indirect generation of the partial width of the $ω(782)$ meson with respect to the reaction $ω(782) \to ρ(770) π\toπ^+π^-π^0$ within the context of a ``Unitary Effective Resonance Model'' (UERM), which has previously been applied to resonant fermionic field operators, here extended to scalar, pseudoscalar and vector bosonic fields. The $ω(782)$ meson is described by a (quasi-)real field, while the intermediate $ρ(770)$ 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 (QFT). Some aspects of the UERM of (anti-)particles and (anti-)holes are discussed.
