Meson-baryon scattering parameters from lattice QCD with an isospin chemical potential
Meson-baryon scattering parameters from lattice QCD with an isospin chemical potential
The extraction of meson-baryon scattering parameters from lattice QCD is complicated by the necessity, in some channels, of including annihilation diagrams. We consider a strategy to avoid the need for these extremely costly and noisy contributions. The strategy is based on simulations with an isospin chemical potential which, contrary to …
