✦ Synopsis
We investigate the indirect generation of the partial width of the ω(782) meson with respect to the reaction ω(782) → ρ(770)π → π + 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.
