General Hamiltonian Approach to the -Body Finite-Volume Formalism: Extracting the Resonance Parameters from Lattice QCD

Kang Yu, Derek B. Leinweber, Anthony W. Thomas +3

We present a nonperturbative Hamiltonian framework (NPHF) to address the general -body problem. This framework rigorously connects finite-volume spectra from lattice QCD to scat…

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…

Spectral parameters of the resonance from lattice QCD

Zhengli Wang, Derek B. Leinweber, Chuan Liu +6

We present a lattice QCD investigation of the resonance using nine Wilson-Clover ensembles with three lattice spacings and various pion masses ranging from …

Exploring the spectrum in lattice QCD

Liam Hockley, Waseem Kamleh, Derek Leinweber +1

We present an exploratory lattice QCD analysis of the -baryon spectrum. Using smeared three-quark operators in a correlation matrix analysis, we report masses for the ground, f…

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 which…

Understanding the nature of baryon resonances

Derek B. Leinweber, Curtis D. Abell, Liam C. Hockley +5

This presentation opens with a brief review of lattice QCD calculations showing the radial excitation of the nucleon sits at approximately 2 GeV, well above the Roper resonanc…

Searching for the first radial excitation of the in lattice QCD

Liam Hockley, Waseem Kamleh, Derek Leinweber +1

We present a lattice QCD analysis of the -baryon spectrum, with the goal of finding the position of the radial excitation of the ground state. Using smeared…

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 are…
