The past decades witnessed the golden era of hadron physics. Many excited open heavy
flavor mesons and baryons have been observed since 2017. We shall provide an updated …

Chiral perturbation theory for heavy hadrons and chiral effective field theory for heavy hadronic molecules

L Meng, B Wang, GJ Wang, SL Zhu - Physics Reports, 2023 - Elsevier
Chiral symmetry and its spontaneous breaking play an important role both in the light
hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …

Precision studies of QCD in the low energy domain of the EIC

VD Burkert, L Elouadrhiri, A Afanasev… - Progress in particle and …, 2023 - Elsevier
Abstract This White Paper aims at highlighting the important benefits in the science reach of
the EIC. High luminosity operation is generally desirable, as it enables producing and …

Hadronic molecules in decays

HX Chen - Physical Review D, 2022 - APS
There are eighteen possibly existing D (*) D¯(*), D (*) K¯(*), and D (*) D s (*)-hadronic
molecular states. We construct their corresponding interpolating currents and calculate their …

Spectrum of hidden-charm, open-strange exotics in the dynamical diquark model

JF Giron, RF Lebed, SR Martinez - Physical Review D, 2021 - APS
The observation by BESIII and LHCb of states with hidden charm and open strangeness
(cc¯ qs¯) presents new opportunities for the development of a global model of heavy-quark …

Hidden-charm tetraquarks with strangeness in the chiral quark model

G Yang, J Ping, J Segovia - Physical Review D, 2021 - APS
The hidden-charm tetraquarks with strangeness, cc¯ sq¯(q= u, d), in JP= 0+, 1+, and 2+ are
systematically investigated in the framework of real-and complex-scaling range of a chiral …

Implications of the Zcs (3985) and Zcs (4000) as two different states

L Meng, B Wang, GJ Wang, SL Zhu - Science Bulletin, 2021 - Elsevier
Recently, the hidden charm tetraquark states Z cs (3985) and Z cs (4000) with strangeness
were observed by the BESIII and LHCb collaborations, respectively, which are great …

Axial meson exchange and the and resonances as heavy hadron molecules

MJ Yan, FZ Peng, M Sánchez Sánchez… - Physical Review D, 2021 - APS
Early speculations about the existence of heavy hadron molecules were grounded on the
idea that light-meson exchange forces could lead to binding. In analogy to the deuteron, the …

Exotic molecular states and tetraquark states with

QN Wang, W Chen, HX Chen - arXiv preprint arXiv:2011.10495, 2020 - arxiv.org
We have calculated the mass spectra for the $\bar {D} _s^{(*)} D^{(*)} $ molecular states and
$ sc\bar q\bar c $ tetraquark states with $ J^ P= 0^+, 1^+, 2^+ $. The masses of the axial …

Predicting the D‾ s (*) Ds (*) bound states as the partners of X (3872)

L Meng, B Wang, SL Zhu - Science Bulletin, 2021 - Elsevier
In this work, we investigate the SU (3) flavor symmetry, heavy quark spin symmetry and their
breaking effects in the di-meson systems. We prove the existence of the [D‾ s∗ D s∗] 0++,[D‾ …
