Two-nucleon systems at MeV from lattice QCD
Kuan Zhang, Kang Yu, Yiqi Geng +5
Nucleon-nucleon systems in the and the channels are studied in lattice quantum chromodynamics at a pion mass of approximately MeV, employing three $…
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 …
Finite Volume Hamiltonian method for two-particle systems containing long-range potential on the lattice
Kang Yu, Guang-Juan Wang, Jia-Jun Wu +1
We propose a systematic method to block-diagonalize the finite volume effective Hamiltonian for two-particle systems with arbitrary spin in both the rest and moving frame. The fram…
Study of the pion-mass dependence of -meson properties in lattice QCD
Kang Yu, Yan Li, Jia-Jun Wu +2
We collect spectra extracted in the sector provided by various lattice QCD collaborations and study the dependence of -meson properties using Hamiltonian E…
