Abstract

Full O(g) meson wavefunctions are constructed in the context of Perturbative Cavity Dynamics. In addition to the valence [Formula: see text] state these wavefunctions contain [Formula: see text] (Bremsstrahlung) and [Formula: see text] (vacuum fluctuation) configurations. The divergent O(g2) self-energy contributions to the ground state energy are regulated by truncating the basis size and demanding that the bound state mass be independent of the cut-off parameter. This regularization procedure results in a nontrivial cut-off dependence of the model parameters. Parameter functions are computed for the light mesons π-ρ, K-K* and ϕ.
