A Paradigm for the Coupled-Channel Origin of Resonances: the Exotic in
Zhi Yang, Guang-Juan Wang, Jia-Jun Wu +1
The state observed in the decay provides direct evidence for an isovector open-charm tetraquark state with strangeness--a discover…
Systematic Study of Coupled-Channel Dynamics in Doubly Heavy Hadronic Molecules
Yu-Shan Ren, Guang-Juan Wang, Zhi Yang +1
Heavy Quark Spin Symmetry (HQSS) is widely use to predict heavy molecules by extending the effective interactions fitted from low-lying states to heavier sectors. In this work, we…
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…
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…
