Higher-order chiral Lagrangians with vector meson nonet in different representations

Wei Guo, Qin-He Yang, Shao-Zhou Jiang

In this paper, chiral Lagrangians with vector meson nonet are constructed across multiple representations, including those to the next-to-leading order in the vector-field represen…

On the quantum numbers of the $X (1880)$

Qin-He Yang, Ling-Yun Dai, Ulf-G. MeiÃner

We study the properties of the $X (1880)$ , the structure around the $p ˉ p$ threshold that appears in the $3 (I ¨ ^{+} I ¨ ^{-})$ invariant mass spectrum in the decay process of $J/Ï\to Î…

New insights into the doubly charmed exotic mesons

Di Guo, Qin-He Yang, Ling-Yun Dai +1

Using effective Lagrangians constrained by the heavy quark spin symmetry and chiral symmetry, for the light quarks, we analyze the $D^{0} D^{0} I ¨ ^{+}$ , $D ˉ^{0} D^{0} I ¨ ^{0}$ and $D^0\bar{D}…
