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…
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…
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…
