Threshold Resonances - a Lattice Perspective

Nuclear Theory 2017-08-23 v1 High Energy Physics - Lattice

Abstract

The calculation of the masses of the lightest nucleon resonances using lattice QCD is surveyed. Recent results for the mass of the first radial excitation of the nucleon, the Roper resonance, are reviewed and the interpretation in terms of models of hadronic resonances, such as the quark model and hadronic molecules, discussed. The talk concludes with an outline of prospects for future calculations.
