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 $b \to s ℓℓ$ decays

Shuang-Yi Li, Rui-Xiang Shi, Li-Sheng Geng

The recent measurements of $R_{K^{+}}$ , $R_{K_{S}^{0}}$ , $R_{K^{*+}}$ , $B_{s} \to μ^{+} μ^{-}$ , a set of CP-averaged angular observables for the $B^{0} \to K^{* 0} μ^{+} μ^{-}$ decay, and its isospin partn…

Understanding $P_{cs} (4459)$ as a hadronic molecule in the $Ξ_{b}^{-} \to J / ψ Λ K^{-}$ 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., $P_{cs} (4459)$ , in the $J / ψ Λ$ invariant mass distribution of t…

Magnetic moments of the spin- $\frac{3}{2}$ doubly charmed baryons in covariant baryon chiral perturbation theory

Rui-Xiang Shi, Li-Sheng Geng

Inspired by the discovery of the spin- $\frac{1}{2}$ doubly charmed baryon $Ξ_{cc}^{++}$ and the subsequent theoretical studies of its magnetic moments, we study the magnetic moment…

Li-Sheng Geng, Benjamín Grinstein, Sebastian Jäger +3

Motivated by renewed evidence for new physics in $b \to s ℓℓ$ transitions in the form of LHCb's new measurements of theoretically clean lepton-universality ratios and the pure…
