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…
Resonance sum rules: an application to the square well potential
Zi-Xi Ou-Yang, Philipp Gubler, Makoto Oka +2
We propose an extension of the Quantum Chromodynamics (QCD) sum rules, termed the Resonance sum rules (RSR), to access resonance poles in the complex energy plane. By strategically…
A Three-Coupled-Channel Analysis of Involving , , and
Kang Yu, Guang-Juan Wang, Jia-Jun Wu +1
In this work, we conduct a three-coupled-channel analysis of the structure, focusing on the , , and channels, based on the one-boson exchan…
