A pion-driven near-threshold enhancement in the $π T_{cc}$ system

Pedro Brandão, Jorgivan Morais Dias, Luciano M. Abreu

Hadronic molecules are commonly viewed as products of near-threshold two-body dynamics. We investigate whether an experimentally established molecule can also serve as a building b…

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…

The $D_{s 1} (2460) \to D_{s} I ¨ ^{+} I ¨ ^{-}$ decay from a $D_{s 1}$ molecular perspective

L. Roca, J. M. Dias, E. Oset

We conduct a theoretical study of the $D_{s 1} (2460) \to D_{s} I ¨ ^{+} I ¨ ^{-}$ decay from the perspective that the $D_{s 1}$ is a molecular state, built mostly from the $D^{*} K$ and $D_s^*…

Dispersive analysis of the isospin breaking in the $X (3872) \to J / I ¨ I ¨ ^{+} I ¨ ^{-}$ and $X (3872) \to J / I ¨ I ¨ ^{+} I ¨ ^{0} I ¨ ^{-}$ decays

Jorgivan Morais Dias, Teng Ji, Xiang-Kun Dong +5

We analyze the latest LHCb data on the $I ¨ ^{+} I ¨ ^{-}$ spectrum in the isospin-violating $X (3872) \to J / I ¨ I ¨ ^{+} I ¨ ^{-}$ decay, based on dispersion theory to deal with the $I ¨ I ¨ $ final state…

Jing Song, Wei-Hong Liang, Chu-Wen Xiao +2

We report on the reactions $I ¨ (3770) \to I^ˉ c ◯^{+} K ˉ I^$ and $I ¨ (3770) \to I^ˉ c ◯^{+} K ˉ I^^{*} (1530) (I^^{*} (1530) \to I ¨ I^$ ), and calculate the mass distributions $\frac{{\rm d}Î…
