We present a measurement of the azimuthal asymmetries two charged pions in inclusive process e^{+}e^{-}→ππX, based on data set 62 pb^{-1} at center-of-mass energy 3.65 GeV collected with BESIII detector. These can be attributed to Collins fragmentation function. observe nonzero asymmetry, which increases increasing pion momentum. As our scale is close that existing semi-inclusive deep inelastic scattering experimental data, measured are important inputs for global analysis extracting quark...
Based on a sample of $(1310.6\ifmmode\pm\else\textpm\fi{}10.5)\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $J/\ensuremath{\psi}$ events collected with the BESIII detector operating at BEPCII storage ring, partial wave analysis decay $J/\ensuremath{\psi}\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\phi}\ensuremath{\phi}$ is performed in order to study intermediate states. Results show that structures are predominantly ${0}^{\ensuremath{-}+}$ The existence $\ensuremath{\eta}(2225)$...

Using $482\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of data taken at $\sqrt{s}=4.009\text{ }\mathrm{GeV}$, we measure the branching fractions decays ${D}^{*0}$ into ${D}^{0}{\ensuremath{\pi}}^{0}$ and ${D}^{0}\ensuremath{\gamma}$ to be $\mathcal{B}({D}^{*0}\ensuremath{\rightarrow}{D}^{0}{\ensuremath{\pi}}^{0})=(65.5\ifmmode\pm\else\textpm\fi{}0.8\ifmmode\pm\else\textpm\fi{}0.5)%$...
Based on 2.93 fb^{-1} e^{+}e^{-} collision data taken at center-of-mass energy of 3.773 GeV by the BESIII detector, we report searches for singly Cabibbo-suppressed decays D^{+}→ωπ^{+} and D^{0}→ωπ^{0}. A double tag technique is used to measure absolute branching fractions B(D^{+}→ωπ^{+})=(2.79±0.57±0.16)×10^{-4} B(D^{0}→ωπ^{0})=(1.17±0.34±0.07)×10^{-4}, with statistical significances 5.5σ 4.1σ, where first second uncertainties are systematic, respectively.
Using 4.479×10^{8} ψ(3686) events collected with the BESIII detector, we search for decays ψ(3686)→e^{+}e^{-}χ_{cJ} and χ_{cJ}→e^{+}e^{-}J/ψ, where J=0, 1, 2. The χ_{cJ}→e^{+}e^{-}J/ψ are observed first time. measured branching fractions B(ψ(3686)→e^{+}e^{-}χ_{cJ})=(11.7±2.5±1.0)×10^{-4}, (8.6±0.3±0.6)×10^{-4}, (6.9±0.5±0.6)×10^{-4} 2, B(χ_{cJ}→e^{+}e^{-}J/ψ)=(1.51±0.30±0.13)×10^{-4}, (3.73±0.09±0.25)×10^{-3}, (2.48±0.08±0.16)×10^{-3} respectively. ratios of...

Domain generalization person re-identification (DG-ReID) has gained much attention recently due to the poor performance of supervised on unseen domains. The goal domain is develop a model that insensitive bias and can perform well across different In this article, We conduct experiments verify importance style factors in bias. Specifically, are affirm domains significantly contributes Based observation, we propose variable irrelevant learning (SVIL) eliminate influence model. employ jitter...
This Letter presents results of a search for the mixing sub-eV sterile neutrino based on full data sample Daya Bay Reactor Neutrino Experiment, collected during 3158 days detector operation, which contains $5.55 \times 10^{6}$ reactor \anue candidates identified as inverse beta-decay interactions followed by neutron-capture gadolinium. The result was obtained in minimally extended 3+1 model. analysis benefits from doubling statistics our previous and improvements several important systematic...
Symmetrized Kullback-Leibler (KL) information (\(I_{\mathrm{SKL}}\)), which symmetrizes the traditional mutual by integrating Lautum information, has been shown as a critical quantity in communication~\cite{aminian2015capacity} and learning theory~\cite{aminian2023information}. This paper considers problem of computing capacity terms \(I_{\mathrm{SKL}}\) for fixed discrete channel. Such maximization is reformulated into quadratic optimization with simplex constraint. One major challenge here...
