Unexpected large relative strong phase and search for isospin breaking and $C P$ asymmetries in $J/ψ\to K^*(892)\bar K

BESIII Collaboration, M. Ablikim, M. N. Achasov +766

Using a direct scan of 26 energy points near the $J / ψ$ resonance, we perform the first measurement of the relative phase $ϕ_{γ, 3 g}$ between the strong and electromagnetic amplitud…

A Unified Zeroth-Order Approach for Decentralized Minimax Optimization

Haoyuan Cai, Yike Zhao, Aleksandar Armacki +2

We propose ZOMA, a unified Zeroth-Order decentralized accelerated MinimAx framework for multi-agent nonconvex Polyak--Łojasiewicz minimax optimization. The proposed framework only…

Updated measurement of the branching fraction of $D_{s}^{+} \to τ^{+} ν_{τ}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +703

Using a dataset of 7.33 fb $^{- 1}$ of $e^{+} e^{-}$ annihilation data collected with the BESIII detector at center-of-mass energies from 4.128 to 4.226 GeV, we report an updated measure…
