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…
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 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…
