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…
