Static-light meson spectroscopy with optimal distillation profiles
Abstract
The spectrum of static-light and static-charm mesons is studied using optimized distillation in two different Nf = 3 + 1 QCD ensembles with pion masses of mπ ≈ 800 \, MeV and mπ ≈ 420 \,MeV and a heavy (charm) quark. Local and derivative-based operators are used to access states of multiple quantum numbers. The use of optimal profiles is shown to improve the overlap with the energy states compared to standard distillation.
