In this paper, we present a review of recent works on weak decay of heavy mesons and
baryons with two mesons, or a meson and a baryon, interacting strongly in the final state …

QCD sum rules approach to the X, Y and Z states

RM Albuquerque, JM Dias… - Journal of Physics G …, 2019‏ - iopscience.iop.org
In the past decade, due to the experimental observation of many charmonium-like states,
there has been a revival of hadron spectroscopy. In particular, the experimental observation …

Observation of the Resonant Character of the State

Quarkonium hybrids with nonrelativistic effective field theories

M Berwein, N Brambilla, J Tarrús Castellà, A Vairo - Physical Review D, 2015‏ - APS
We construct a nonrelativistic effective field theory description of heavy quarkonium hybrids
from QCD. We identify the symmetries of the system made of a heavy quark, a heavy …

study both the vector and axialvector $ QQ\bar {Q}\bar {Q} $ tetraquark states with the QCD …

Analysis of the Z (4430) as the first radial excitation of the Zc (3900)

ZG Wang - Communications in Theoretical Physics, 2015‏ - iopscience.iop.org
In this article, we take the Z c (3900) and Z (4430) as the ground state and the first radial
excited state of the axial-vector tetraquark states with J PC= 1+−, respectively, and study …
