General Hamiltonian Approach to the $N$ -Body Finite-Volume Formalism: Extracting the $I ¨ $ 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 $N$ -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 $I^c ◯^{-} (2012)$ with Hamiltonian Effective Field Theory

Fang-Chao Han, Zhan-Wei Liu, Derek B. Leinweber +1

We investigate the internal structure of the $I^c ◯ (2012)^{-}$ by analyzing lattice QCD simulation and experimental data within Hamiltonian effective field theory, considering both $J^P…

Spectral parameters of the $I ¨ $ resonance from lattice QCD

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

We present a lattice QCD investigation of the $I ¨ $ resonance using nine $N_{f} = 2 + 1$ Wilson-Clover ensembles with three lattice spacings and various pion masses ranging from $135$ …
