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 $N$ -Body Finite-Volume Formalism: Extracting the $ω$ 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…

A Paradigm for the Coupled-Channel Origin of Resonances: the Exotic $T_{c s ˉ}$ in $D_{s 1} (2460/2536) \to D_{s} π π$

Zhi Yang, Guang-Juan Wang, Jia-Jun Wu +1

The $T_{c s ˉ}$ state observed in the decay $D_{s 1} (2460)^{+} \to D_{s}^{+} π^{+} π^{-}$ provides direct evidence for an isovector open-charm tetraquark state with strangeness--a discovery…

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…

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…

A Three-Coupled-Channel Analysis of $Z_{c} (3900)$ Involving $D D ˉ^{*}$ , $π J / ψ$ , and $ρ η_{c}$

Kang Yu, Guang-Juan Wang, Jia-Jun Wu +1

In this work, we conduct a three-coupled-channel analysis of the $Z_{c} (3900)$ structure, focusing on the $D D ˉ^{*}$ , $J / ψ π$ , and $ρ η_{c}$ channels, based on the one-boson exchange m…

Investigation on the bottom analogs of the $T_{cc}^{+}$

Yu-Shan Ren, Guang-Juan Wang, Zhi Yang +1

We investigate the doubly bottom state $T_{bb}^{-}$ composed of two bottom mesons with $J^{P} = 1^{+}$ . The potentials are obtained using the one-boson exchange model. With the heavy quark…
