Latest results from lattice QCD for the Roper resonance
Shoichi Sasaki (Univ. of Tokyo)🇯🇵
Abstract
The present status of the Roper resonance in lattice QCD is reviewed. Some of the latest lattice results are discussed with particular emphasis on a large systematic error stemming from the finite size effect. These results suggest that the Roper resonance can be described by the simple three quark excitation of sizable extent.
