Study on contributions of hadronic loops to decays of $J / ψ \to$ vector $+$ pseudoscalar mesons

Xiang Liu, Xiao-Qiang Zeng, Xue-Qian Li

In this work, we evaluate the contributions of the hadronic loops to the amplitudes of $J / ψ \to P V$ where $P$ and $V$ denote light pseudoscalar and vector mesons respectively. By fi…

$Λ_{c}^{+} (2940)$ : A Possible Molecular State?

Xiao-Gang He, Xue-Qian Li, Xiang Liu +1

A new baryonic state $Λ_{c} (2940)^{+}$ has recently been discovered by the Babar collaboration in the $D^{0} p$ channel. Later Belle collaboration also observed this state in the $Σ…

X(1812) in Quarkonia-Glueball-Hybrid Mixing Scheme

Xiao-Gang He, Xue-Qian Li, Xiang Liu +1

Recently a $J^{P C} = 0^{++}$ (X(1812)) state with a mass near the threshold of $ω$ and $ϕ$ has been observed by the BES collaboration in $J / ψ \to γ ω ϕ$ decay. It has been suggested tha…

New Members in the $0^{+}$ ( $0^{++})$ Family

Xiao-Gang He, Xue-Qian Li, Xiang Liu +1

Recent BES data on $J / ψ \to ϕ π π$ indicate that there is a possible new spin-0 state ( $f_{0} (1790)$ ) with a mass of $m = 179 0_{- 30}^{+ 40} MeV / c^{2}$ . Assuming it to be an…

Possible Molecular Structure of the Newly Observed Y(4260)

Xiang Liu, Xiao-Qiang Zeng, Xue-Qian Li

We suggest that the newly observed resonance Y(4260) is a $χ_{c} - ρ^{0}$ molecule, which is an isovector. In this picture, we can easily interpret why $Y (4260) \to π^{+} π^{-} J / ψ$ has a lar…

Mixing of Pentaquark and Molecular States

Xiao-Gang He, Xue-Qian Li, Xiang Liu +1

There are experimental evidences for the existence of narrow states $Θ^{+}$ and $Θ_{c}$ with the same quantum numbers of $uu dd s ˉ$ and $uu dd c ˉ$ pentaquarks and also $N K^{(*)}$ a…
