Heavy Meson Masses in the ε-Regime of HMχPT
arXiv:1108.0120 · doi:10.1103/PhysRevD.85.014508
Abstract
The pseudoscalar and vector heavy meson masses are calculated in the ε-regime of Heavy Meson Chiral Perturbation Theory to order ε^4. The results of this calculation will allow the determination of low-energy coefficients (LECs) directly from Lattice QCD calculations of the heavy mesons masses for lattices that satisfy the ε-regime criteria. In particular, the LECs that parametrize the NLO volume dependance of the heavy meson masses are necessary for evaluating the light pseudoscalar meson (π, K, η) and heavy meson ({D^0, D^+, D^+_s}, {B^-,\bar{B}^0,\bar{B}^0_s}) scattering phase shifts.
