Theoretical description of the $D^{+} \to K ˉ^{0} π^{+} π^{0} π^{0}$ reaction

Zi-Ying Yang, Wen-Hao Jia, Dao-Chong Lin +5

We study the $D^{+} \to K ˉ^{0} π^{+} π^{0} π^{0}$ reaction, which shows two clear structures: the $K ˉ^{* 0}$ and $ρ^{+}$ in the $K ˉ^{0} π^{0}$ and $π^{+} π^{0…

Searching for the $2^{+}$ partner of the $T_{cs 0} (2870)$ in the $B^{-} \to D^{-} D^{0} K_{S}^{0}$ reaction

Jing Song, Zi-Ying Yang, Eulogio Oset

We study the $B^{-} \to D^{-} D^{0} K_{S}^{0}$ reaction, recently analyzed by the LHCb collaboration, where a clear signal for the exotic $T_{cs 0} (2870)$ state has been reported. We call the…

Role of $a_{0} (1710)$ in the $D_{s}^{+} \to I ¨ ^{+} I ¨ , I ¨ ^{+} I ¨ $ decays

Jing Song, Zi-Ying Yang, Eulogio Oset

We look into the $D_{s}^{+} \to I ¨ ^{+} I ¨ $ and $D_{s}^{+} \to I ¨ ^{+} I ¨ $ weak decays recently measured by the BESIII collaboration, which proceed very differently in a first step of the weak d…

$P_{c} (4440)$ and $P_{c} (4457)$ decay into $D ˉ I^£_{c}$ and $D ˉ I^_{c}$ and the spin of the $P_{c}$ states

Zi-Ying Yang, Jing Song, Wei-Hong Liang +1

We address the issue of the width and spin assignment of the $P_{c} (4440)$ and $P_{c} (4457)$ pentaquark states. We calculate the partial decays widths of the particles into $J / I ¨ N$ , $\…

Searching for signals of an exotic $I = 1, J^{P} = 2^{+}$ state of $D^{} K^{}$ nature and the structure of the $P_{c} (4312)$ in the $I^_{b} \to I^£_{c}^{++} D^{-} K^{-}$ reaction

Jing Song, Zi-Ying Yang, Eulogio Oset

This paper investigates the decay process $I^_{b} \to I^£_{c}^{++} D^{-} K^{-}$ with the objective of finding a predicted molecular state with isospin $I = 1$ , $J^{P} = 2^{+}$ of $D^{*} K^{*}$ nature,…
