  "abstract": "We study the Standard Model prediction for the mass difference between the two neutral D meson mass eigenstates, $\\Delta m$. We derive a dispersion relation based on heavy quark effective theory that relates $\\Delta m$ to an integral of the width difference of heavy mesons, $\\Delta\\Gamma$, over varying values of the heavy meson mass. Modeling the $m_D$-dependence of certain D decay partial widths, we investigate the effects of SU(3) breaking from phase space on the mass difference. We find that $\\Delta m$ may be comparable in magnitude to $\\Delta\\Gamma$ in the Standard Model.",
