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 amplitudes in covariant baryon chiral perturbation theory with the extended…
Radiative decays of the as a dynamically generated resonance

Inspired by the latest BESIII measurement of the radiative decay, we systematically study the decays within the chiral unitary approach, where…
femtoscopy and the nature of
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…
puzzle in semi-leptonic decays revisited
Shuang-Yi Li, Jie Xu, Rui-Xiang Shi +2
Inspired by the newly reported differential decay rates by the Belle and Belle II Collaborations, we revisit the puzzle in semi-leptonic $…
Potential signature of new magicity from universal aspects of nuclear charge radii
Dan Yang, Yu-Ting Rong, Rong An +1
Shell quenching phenomena in nuclear charge radii are typically observed at the well-established neutron magic numbers. However, the recent discovery of potential new magic numbers…
Are we close to solving the puzzle of weak radiative hyperon decays?
Rui-Xiang Shi, Li-Sheng Geng
The BESIII experiment at the Beijing Electron Positron collider, run as a ``hyperon factory'', recently reported the first measurement of the asymmetry parameter of the d…
Weak radiative hyperon decays in covariant baryon chiral perturbation theory
Rui-Xiang Shi, Shuang-Yi Li, Jun-Xu Lu +1
Weak radiative hyperon decays, important to test the strong interaction and relevant in searches for beyond the standard model physics, have remained puzzling both experimentally a…
New Physics Searches at Kaon and Hyperon Factories
Evgueni Goudzovski, Diego Redigolo, Kohsaku Tobioka +61
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths…
An Alternate Policy Gradient Estimator for Softmax Policies
Shivam Garg, Samuele Tosatto, Yangchen Pan +2
Policy gradient (PG) estimators are ineffective in dealing with softmax policies that are sub-optimally saturated, which refers to the situation when the policy concentrates its pr…
Discriminating 1D new physics solutions in decays
Shuang-Yi Li, Rui-Xiang Shi, Li-Sheng Geng
The recent measurements of , , , , a set of CP-averaged angular observables for the decay, and its isospin partn…
Understanding as a hadronic molecule in the decay
Jun-Xu Lu, Ming-Zhu Liu, Rui-Xiang Shi +1
Recently, the LHCb Collaboration reported on the evidence for a hidden charm pentaquark state with strangeness, i.e., , in the invariant mass distribution of t…
Magnetic moments of the spin- doubly charmed baryons in covariant baryon chiral perturbation theory
Rui-Xiang Shi, Li-Sheng Geng
Inspired by the discovery of the spin- doubly charmed baryon and the subsequent theoretical studies of its magnetic moments, we study the magnetic moment…
