$∣Δ I ∣ = 3/2$ non-leptonic hyperon decays in covariant baryon chiral perturbation theory

Jie Xu, Jun-Xu Lu, Rui-Xiang Shi +1

Inspired by the recent BESIII measurements of non-leptonic hyperon decays, we reexamine their $∣Δ I ∣ = 3/2$ amplitudes in covariant baryon chiral perturbation theory with the extended…

Radiative decays of the $I^ (1520)$ as a dynamically generated resonance

Rui-Xiang Shi, Yu-Bao Zhang, Jun-Xu Lu +2

Inspired by the latest BESIII measurement of the $I^ (1520) \to I^^{3} I^£^{0}$ radiative decay, we systematically study the decays $I^ (1520) \to I^^{3} I^ (I^£^{0})$ within the chiral unitary approach,…

$J / I ¨ I^$ femtoscopy and the nature of $P_{I ¨ s}^{I^} (4338)$

Yi-Bo Shen, Zhi-Wei Liu, Ming-Zhu Liu +4

Over the past two decades, numerous exotic hadron states have been discovered, yet their underlying nature remains unclear. It is widely acknowledged that understanding hadron-hadr…

$V_{c b}$ puzzle in semi-leptonic $B \to D^{*}$ decays revisited

Shuang-Yi Li, Jie Xu, Rui-Xiang Shi +2

Inspired by the newly reported $B \to D^{*} (\to D I ¨ ) ℓ I^ˉ ½_{ℓ}$ differential decay rates by the Belle and Belle II Collaborations, we revisit the $V_{c b}$ puzzle in semi-leptonic…
