Hadronic molecules

FK Guo, C Hanhart, UG Meißner, Q Wang, Q Zhao… - Reviews of Modern …, 2018 - APS
A large number of experimental discoveries especially in the heavy quarkonium sector that
did not meet the expectations of the until then very successful quark model led to a …

Heavy-quark QCD exotica

RF Lebed, RE Mitchell, ES Swanson - Progress in Particle and Nuclear …, 2017 - Elsevier
This review presents an overview of the remarkable progress in the field of heavy-quark
exotic hadrons over the past 15 years. It seeks to be pedagogical rather than exhaustive …

A survey of heavy–heavy hadronic molecules

XK Dong, FK Guo, BS Zou - Communications in Theoretical …, 2021 - iopscience.iop.org
The spectrum of hadronic molecules composed of heavy–antiheavy charmed hadrons has
been obtained in our previous work. The potentials are constants at the leading order, which …

A survey of heavy-antiheavy hadronic molecules

XK Dong, FK Guo, BS Zou - arXiv preprint arXiv:2101.01021, 2021 - arxiv.org
Many efforts have been made to reveal the nature of the overabundant resonant structures
observed by the worldwide experiments in the last two decades. Hadronic molecules attract …

The hidden-charm pentaquark and tetraquark states

HX Chen, W Chen, X Liu, SL Zhu - Physics Reports, 2016 - Elsevier
In the past decade many charmonium-like states were observed experimentally. Especially
those charged charmonium-like Z c states and bottomonium-like Z b states cannot be …

Observation of a Charged (DD¯*)±Mass Peak in e+ e−→ π DD¯* at s= 4.26 GeV

M Ablikim, MN Achasov, O Albayrak, DJ Ambrose… - Physical review …, 2014 - APS
We report on a study of the process e+ e−→ π±(DD¯*)∓ at s= 4.26 GeV using a 525 pb− 1
data sample collected with the BESIII detector at the BEPCII storage ring. A distinct charged …

Study of the ψ2 (3823) and χc1 (3872) states in B+→(J/ψπ+ π−) K+ decays

R Aaij, C Abellán Beteta, T Ackernley, B Adeva… - Journal of High Energy …, 2020 - Springer
A bstract The decays B+→ J/ψπ+ π− K+ are studied using a data set corresponding to an
integrated luminosity of 9 fb− 1 collected with the LHCb detector in proton-proton collisions …

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 …

Glueballs, hybrids, multiquarks: Experimental facts versus QCD inspired concepts

E Klempt, A Zaitsev - Physics Reports, 2007 - Elsevier
Glueballs, hybrids and multiquark states are predicted as bound states in models guided by
quantum chromo dynamics (QCD), by QCD sum rules or QCD on a lattice. Estimates for the …

Observation of a Resonancelike Structure in the Mass Distribution <?format ?>in Exclusive Decays

SK Choi, SL Olsen, I Adachi, H Aihara, V Aulchenko… - Physical review …, 2008 - APS
A distinct peak is observed in the π±ψ′ invariant mass distribution near 4.43 GeV in B→ K
π±ψ′ decays. A fit using a Breit-Wigner resonance shape yields a peak mass and width of …
