Hadron Scattering From Lattice QCD
Prof. Christian Lang (Univ. Graz / Österreich)
The formulation of QCD on a space-time lattice has become a prime tool for QCD calculations in the non-perturbative regime. For a long time one was restricted to treating resonances like stable states. Recently new tools have been developed, that allow to study resonance decays and even phase shifts in this ab initio approach. I will discuss basics of the general methods as well as recent results in the light and heavy meson sector and in meson-baryon systems.
