Abstract

We predict for M_{ρ{variant}⁺}-M_{ρ{variant} ⁰} the values -3.4 ± 0.8 MeV using the ρ{variant}-ω mixing and the quark model, respectively. The extracted parameters indicate the necessity of a relativistic treatment of the old mesons. The problem of extrapolating these parameters to the charmed mesons is discussed. Under conservative assumptions, we predict 1.7 ≤ M_D⁰ ≤ 2.2 MeV and -1.4 ± 1.1 ≤ M_D^*+- M_D^*0 ≤ 0.0 ± 0.6 MeV.
