The $I^c ◯ (2380)$ as a partner of the $I^c ◯ (2012)$

Yi-Yao Li, Albert Feijoo, Eulogio Oset

We present a study of the $I^c ◯ (2380)$ resonance and show that it is consistent with a dynamically generated state arising from the $K ˉ^{*} I^^{*}$ , $I ¨ I^c ◯$ , and $I ¨ I^c ◯$ interactions.…

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 $…

Revisiting the $I^_{c}^{+} \to K ˉ^{0} I^\cdot p$ reaction: the role of $N^{} (1535), N^{} (1650)$ and $I^£ (1620)$

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

We perform a theoretical study of the weak decay $I^_{c}^{+} \to K ˉ^{0} I^\cdot p$ using a coupled-channel chiral unitary approach that incorporates both pseudoscalar-baryon and v…

Molecular states with bottom mesons and multistrange baryons systems

Jing Song, Yi-Yao Li, Eulogio Oset

We investigate molecular states formed by bottom mesons and multistrange baryons from both octet and decuplet flavor representations, using the local hidden gauge approach combined…

The $I^_{c}^{+} \to I^ I ¨ ^{+} I ¨ ^{+} I ¨ ^{-}$ reaction, and a triangle singularity producing the $I^£^{*} (1430)$ state

Yi-Yao Li, Jing Song, Eulogio Oset +2

We study the decay $I^_{c}^{+} \to I^ I ¨ ^{+} I ¨ ^{+} I ¨ ^{-}$ , focusing on the production of the $I^£^{*} (1430)$ resonance observed by the Belle Collaboration. Interpreted as a dynamically generat…
