Alternative calculation of the physical mass of the p-meson
We have derived an expression for the physical mass and width of the ρ-meson in vacuum from its spectral function, calculated in the vector meson dominance model when a ρ 0 meson couples to two virtual pions π +–π −. The propagator is computed after evaluating the ρ-meson self-energy. The real part...
