Heavy-meson masses in the ε regime of heavy-meson chiral perturbation theory

The pseudoscalar and vector heavy-meson masses are calculated in the epsilon-regime of Heavy Meson Chiral Perturbation Theory to order epsilon(4). The results presented will allow the determination of low-energy coefficients (LECs) directly from Lattice QCD calculations of the heavy-mesons masses for lattices that satisfy the epsilon-regime criteria. In particular, the LECs that parametrize the next-to-leading order volume dependence of the heavy-meson masses are necessary for evaluating the light-pseudoscalar meson (pi, K, eta) and heavy meson ({D-0, D+, D-s(+)}, {B-, (B) over bar (0), (B) over bar (0)(s)}) scattering phase shifts.
