Heavy-light mesons in the epsilon-regime

Understand

We study the finite-size scaling of heavy-light mesons in the static limit.

• We compute two-point functions of chiral current densities as well as pseudoscalar densities in the epsilon-regime of heavy meson Chiral Perturbation Theory (HMChPT).
• As expected, finite volume dependence turns out to be significant in this regime and can be predicted in the effective theory in terms of the infinite-volume low-energy couplings.
• These results might be relevant for extraction of heavy-meson properties from lattice simulations.
