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

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

Using a direct scan of 26 energy points near the $J / I ¨ $ resonance, we perform the first measurement of the relative phase $I ¨ _{I^^{3}, 3 g}$ between the strong and electromagnetic ampli…

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--Åojasiewicz minimax optimization. The proposed framework only…

Updated measurement of the branching fraction of $D_{s}^{+} \to I ¨ ^{+} I^½_{I ¨} $

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…

Search for massive, long-lived particles in events with displaced vertices and displaced muons in $pp$ collisions at $s = 13.6$ TeV with the ATLAS experiment

ATLAS Collaboration

A search is presented for massive long-lived particles in events featuring at least one displaced vertex and at least one displaced muon, using proton-proton collision data collect…

Measurement of the top-quark mass using decays with a $J / I ¨ $ meson at $s =$ 13 TeV with the ATLAS detector

ATLAS Collaboration

The top-quark mass is measured using top-quark decays producing an isolated lepton and $J / I ¨ $ meson reconstructed in its $I^¼^{+} I^¼^{-}$ decay mode. The data sample was recorded with th…
