About this document
Lattice QCD Study of ∆(1232) Resonance by gypaetus is a document available to read on EtoBox.
This document presents a study of the P-wave nucleon-pion scattering amplitude in the ∆(1232) resonance channel using lattice QCD and the Lüscher method. The authors determine the resonance parameters, including the resonance mass and coupling, through calculations performed on a lattice with Nf = 2 + 1 flavors of clover fermions. The results indicate a resonance mass of m∆ = 1378(7)(9) MeV and a coupling g∆-πN = 23.8(2.7)(0.9).
