We present a study of the process e+e−→π±(DD¯*)∓ using data samples 1092 pb−1 at s=4.23 GeV and 826 s=4.26 collected with BESIII detector BEPCII storage ring. With full reconstruction D meson pair bachelor π± in final state, we confirm existence charged structure Zc(3885)∓ (DD¯*)∓ system two isospin processes e+e−→π+D0D*− e+e−→π+D−D*0. By performing simultaneous fit, statistical significance signal is determined to be greater than 10σ, its pole mass width are measured...
Using data samples collected with the BESIII detector at BEPCII collider, we measure Born cross section of ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}p\overline{p}$ 12 center-of-mass energies from 2232.4 to 3671.0 MeV. The corresponding effective electromagnetic form factor proton is deduced under assumption that electric and magnetic factors are equal $(|{G}_{E}|=|{G}_{M}|)$. In addition, ratio factors, $|{G}_{E}/{G}_{M}|$, $|{G}_{M}|$ extracted by fitting polar angle distribution...
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 $\ensuremath{\eta}(2225)$...
An amplitude analysis of the $\pi^{0}\pi^{0}$ system produced in radiative $J/\psi$ decays is presented. In particular, a piecewise function that describes dynamics determined as $M_{\pi^{0}\pi^{0}}$ from an $(1.311\pm0.011)\times10^{9}$ collected by BESIII detector. The goal this to provide description scalar and tensor components $\pi^0\pi^0$ while making minimal assumptions about properties or number poles amplitude. Such model-independent allows one integrate these results with other...
This paper summarizes the main detection technologies for highway pavement cracks and judgment methods crack width, introduces existing evaluation standards metrological verification systems. For acquisition of linear array equipment is mainly used, its ability based on images, adopting manual interpretation method. Automatic identification still need further research demonstration. looks forward to development trend method width in future, aiming improve automation degree judgment, optimize...
Using $1.31 \times 10^9$ $J/\psi$ events collected by the BESIII detector at BEPCII $e^+e^-$ collider, we report first observation of $h_1(1380)$ in $J/\psi \to \eta^{\prime} h_1(1380)$ with a significance more than ten standard deviations. The mass and width possible axial-vector strangeonium candidate are measured to be $M = (1423.2 \pm 2.1 7.3)\mevcc$ $\Gamma (90.3 9.8 17.5)\mev$. product branching fractions, assuming no interference, determined $\mathcal{B}(J/\psi \eta^{\prime}h_1(1380))...
By analyzing 482 pb$^{-1}$ of $e^+e^-$ collision data collected at the center-of-mass energy $\sqrt s=4.009$ GeV with BESIII detector, we measure %absolute branching fractions for semi-leptonic decays $D_{s}^{+}\to \phi e^{+}\nu_{e}$, $\phi \mu^{+}\nu_{\mu}$, $\eta \mu^{+}\nu_{\mu}$ and $\eta'\mu^{+}\nu_{\mu}$ to be ${\mathcal B}(D_{s}^{+}\to\phi e^{+}\nu_{e})=(2.26\pm0.45\pm0.09)$\%, \mu^{+}\nu_{\mu})=(1.94\pm0.53\pm0.09)$\%, B}(D_{s}^{+}\to\eta \mu^{+}\nu_{\mu})=(2.42\pm0.46\pm0.11)$\%...
