Lattice QCD constraints on pion electroproduction off a nucleon
Yu Zhuge, Zhan-Wei Liu, Derek B. Leinweber +1
Very recently, a lattice QCD collaboration has explored threshold pion electroproduction near the physical pion mass and has simulated the relevant multipole amplitudes. Different…
Structure of the with Hamiltonian Effective Field Theory
Fang-Chao Han, Zhan-Wei Liu, Derek B. Leinweber +1
We investigate the internal structure of the by analyzing lattice QCD simulation and experimental data within Hamiltonian effective field theory, considering both $J^P…
Understanding the nature of the resonance
Liam Hockley, Curtis Abell, Derek Leinweber +1
We present a coupled-channel analysis of the -baryon spectrum, based in the framework of Hamiltonian Effective Field Theory (HEFT). We construct a Hamiltonian whic…
Structure of the resonance
Jiong-Jiong Liu, Zhan-Wei Liu, Kan Chen +4
We examine the internal structure of the through an analysis of lattice QCD simulations and experimental data within Hamiltonian effective field theory. Two scenarios ar…
