Scalar mesons in a finite volume
V. Bernard, M. Lage, U. -G. Meißner +1
Using effective field theory methods, we discuss the extraction of the mass and width of the scalar mesons f0(980) and a0(980) from the finite-volume spectrum in lattice QCD. In pa…
The mass of the Delta resonance in a finite volume: fourth-order calculation
V. Bernard, D. Hoja, U. -G. Meißner +1
We calculate the self-energy of the Delta (1232) resonance in a finite volume, using chiral effective field theory with explicit spin-3/2 fields. The calculations are performed up-…
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…
