as the first -wave open charm vector molecular state?
Martin Cleven, Qian Wang, Feng-Kun Guo +3
Since its first observation in 2005, the vector charmonium has turned out to be one of the prime candidates for an exotic state in the charmonium spectrum. It was recentl…
Heavy Quark Symmetries: Molecular Partners of the X(3872) and
Feng-Kun Guo, Carlos Hidalgo-Duque, Juan Nieves +1
In this work, we have used an Effective Field Theory (EFT) framework based on Heavy Quark Spin (HQSS), Heavy Flavour (HFS) and Heavy Antiquark-Diquark symmetries (HADS). Using a st…
Y(4260): hadronic molecule versus hadro-charmonium interpretation
Qian Wang, Martin Cleven, Feng-Kun Guo +4
In this paper we confront both the hadronic molecule and the hadro-charmonium interpretations of the $\y$ with the experimental data currently available. We conclude that the data…
Tetraquarks, hadronic molecules, meson-meson scattering and disconnected contributions in lattice QCD
Feng-Kun Guo, Liuming Liu, Ulf-G. Meißner +1
There are generally two types of Wick contractions in lattice QCD calculations of a correlation function --- connected and disconnected ones. The disconnected contribution is diffi…
Production of the X(3872) in charmonia radiative decays
Feng-Kun Guo, Christoph Hanhart, Ulf-G. Meißner +2
We discuss the possibilities of producing the X(3872), which is assumed to be a D \bar D^* bound state, in radiative decays of charmonia. We argue that the ideal energy regions to…
Heavy Antiquark--Diquark Symmetry and Heavy Hadron Molecules: Are There Triply Heavy Pentaquarks?
Feng-Kun Guo, Carlos Hidalgo-Duque, Juan Nieves +1
We explore the consequences of heavy flavour, heavy quark spin and heavy antiquark-diquark symmetries for hadronic molecules within an effective field theory framework.. Owing to h…
