Gittersimulationen der Quantenchromodynamik ermöglichen eine vollständig nichtperturbative Berechnung hadronischer Korrelationsfunktionen, allerdings müssen die Beiträge angeregter Zustände unter Kontrolle sein um verlässlich physikalische Grö

Multi-particle states with additional pions are expected to result in a difficult-to-control excited-state contamination in lattice simulations. We show that heavy meson chiral perturbation theory can be employed to estimate the contamination due to

Using Heavy Meson Chiral Perturbation Theory (HMChPT), the $B^* \pi$ excited states contamination of the $B \to \pi$ vector form factors is computed to NLO in the chiral expansion and in the static limit. The results suggest that the excited states f

Multi-particle states with additional pions are expected to result in a non-negligible excited-state contamination in lattice simulations. We show that heavy meson chiral perturbation theory can be employed to calculate the contamination due to two-p
