Correlation function for the $n D ˉ_{s 0}^{*} (2317)$ interaction and the issue of elastic unitarity

Natsumi Ikeno, Eulogio Oset

We study the interaction of a neutron with the $D ˉ_{s 0}^{*} (2317)$ resonance and look at the amplitude below threshold and close above threshold. The study is done from the persp…

On the $I ¨ ^{+} I ¨ ^{-}$ and $D_{s}^{+} I ¨ ^{\pm}$ mass spectra in the $D_{s 1} (2536) \to D_{s}^{+} I ¨ ^{+} I ¨ ^{-}$ decays

Jorgivan Morais Dias, Yi-Yao Li, Eulogio Oset

We have carried out an evaluation of the $I ¨ ^{+} I ¨ ^{-}$ and $D_{s}^{+} I ¨ ^{+}$ mass distributions in the $D_{s 1} (2536)$ decay to $D_{s}^{+} I ¨ ^{+} I ¨ ^{-}$ , from the perspective that the $D_{s1}(253…

$a_{0} (980)$ and $f_{0} (980)$ excitation in the $D^{+} \to I ¨ ^{+} I^\cdot I^\cdot$ decay

Jing Song, Yi-Yao Li, Melahat Bayar +1

We have made a thorough study of the $D^{+} \to I ¨ ^{+} I^\cdot I^\cdot$ reaction, recently measured by the BESIII collaboration, which shows an abnormal strength at high invariant masses in the $…

Study of hidden-charm, doubly-strange pentaquarks in $I^_{b} \to J / I ¨ I^^{-} K^{+}$ and $I^_{b} \to J / I ¨ I^^{-} I ¨ ^{+}$

L. Roca, J. Song, E. Oset

Hidden-charm pentaquark states with double strangeness, $P_{css}$ , have been predicted within the framework of unitary coupled-channel dynamics. In this work, we theoretically inve…

Correlation functions for $n D ˉ_{s 1} (2460)$ and $n D ˉ_{s 1} (2536)$

Breno AgatÃ£o, Pedro BrandÃ£o, A. Martinez Torres +3

We study the interaction of the $n D ˉ_{s 1} (2460)$ and $n D ˉ_{s 1} (2536)$ systems from the perspective that the $D_{s 1} (2460)$ and $D_{s 1} (2536)$ states are molecular sta…

Revisiting the $I^_{c}^{+} \to I^ I^\cdot I ¨ ^{+}$ and the roles of intermediate resonances

En Wang, Wen-Tao Lyu, Man-Yu Duan +4

In this paper, we first review the theoretical and experimental studies of the process $I^_{c}^{+} \to I ¨ ^{+} I^\cdot I^$ . Motivated by the recent BESIII and Belle measurements, we have conduc…
