The Delta-resonance in a finite volume
Véronique Bernard, Ulf-G. Meißner, Akaki Rusetsky
We study the extraction of Delta-resonance parameters from lattice data for small quark masses, corresponding to the case of an unstable Delta. To this end, we calculate the spectr…
Chiral Extrapolations and the Covariant Small Scale Expansion
Véronique Bernard, Thomas R. Hemmert, Ulf-G. Meißner
We calculate the nucleon and the delta mass to fourth order in a covariant formulation of the small scale expansion. We analyze lattice data from the MILC collaboration and demonst…
Baryon masses, chiral extrapolations, and all that
Matthias Frink, Ulf-G. Meißner, Ilka Scheller
We calculate the baryon octet masses to fourth order in chiral perturbation theory employing dimensional and cut-off regularization. We analyze the pion and kaon mass dependences o…
