We observe a narrow enhancement near 2m(p) in the invariant mass spectrum of pp pairs from radiative J/psi-->gammapp decays. No similar structure is seen J/psi-->pi(0)pp The results are based on an analysis 58 x 10(6) event sample J/psi decays accumulated with BESII detector at Beijing electron-positron collider. can be fit either S- or P-wave Breit-Wigner resonance function. In case S-wave fit, peak below M=1859(+3)(-10) (stat)+5-25(syst) MeV/c(2) and total width Gamma<30 90% confidence...
We report values of R = sigma(e(+)e(-)-->hadrons)/sigma(e(+)e(-)-->mu(+)mu(-)) for 85 center-of-mass energies between 2 and 5 GeV measured with the upgraded Beijing Spectrometer at Electron-Positron Collider.
The decay channel J/psi --> gamma(pi)(+)pi(-)eta is analyzed using a sample of 5.8 x 10(7) events collected with the BESII detector. A resonance, Chi(1835), observed in pi(+)pi(-)eta invariant-mass spectrum statistical significance 7.7 sigma. fit Breit-Wigner function yields mass M = 1833.7 +/- 6.1(stat) 2.7(syst) MeV/c(2), width Tau 67.7 20.3(stat) 7.7(syst) and product branching fraction B(J/psi gammaChi) .

Based on 58 million BESII J/psi events, the bar{K}^*(892)^0K^+pi^- channel in K^+K^-pi^+pi^- is studied. A clear low mass enhancement invariant spectrum of K^+pi^- observed. The does not come from background other decay channels, nor phase space. Two independent partial wave analyses have been performed.

Using the BES-II detector at BEPC Collider, we measured lowest order cross sections and R values (R=σe+e−→hadrons0/σe+e−→μ+μ−0) for inclusive hadronic event production center-of-mass energies of 3.650, 3.6648 3.773 GeV. The results lead to R¯uds=2.218±0.019±0.089 which is average these 3.650 GeV GeV, R=3.746±0.037±0.187 s=3.773GeV. We determined section ψ(3770) be σψ(3770)B=(9.323±0.253±0.801)nb branching fractions decays BF(ψ(3770)→D0D¯0)=(49.5±1.3±3.8)%, BF(ψ(3770)→D+D−)=(35.7±1.1±3.4)%...

460 Background: For patients with inoperable oesophageal cancer, simultaneous radiotherapy is the standard treatment option. However, elderly are often unable to tolerate CCRT, so a safe, effective and tolerable option needed. Tegafur, derivative of 5-FU, has shown efficacy safety in cancer. This clinical study evaluated toxicity combined Tegafur bolus Methods: In this study, 62 unresectable intermediate advanced ESCC (stage IIA IVA) between March 2022 February 2024 were screened divided...
The absolute branching fractions for the decays $D^0 \to K^-e ^+\nu_e$ and \pi^-e^+\nu_e$ are determined using $7584\pm 198 \pm 341$ singly tagged $\bar D^0$ sample from data collected around 3.773 GeV with BES-II detector at BEPC. In system recoiling against meson, $104.0\pm 10.9$ events $9.0 3.6$ observed. Those yield to be $BF(D^0 K^-e^+\nu_e)=(3.82 0.40\pm 0.27)%$ \pi^-e^+\nu_e)=(0.33 0.13\pm 0.03)%$. vector form factors $|f^K_+(0)| = 0.78 0.04 0.03$ $|f^{\pi}_+(0)| 0.73 0.14 0.06$....

We report measurements of the continuum R(uds) near center-of-mass energy 3.70 GeV, R[uds(c)+psi(3770)](s) and R(had)(s) values in e(+)e(-) annihilation at 68 points region between 3.650 3.872 GeV with BES-II detector BEPC Collider. obtain for light hadron (containing u, d, s quarks) production DD threshold to be R(uds)=2.141+/-0.025+/-0.085.
The $\pi N$ system in decays of $J/\psi\to\bar NN\pi$ is limited to be isospin 1/2 by conservation. This provides a big advantage studying $N^*\to \pi compared with and $\gamma experiments which mix 3/2 for the system. Using 58 million $J/\psi$ collected Beijing Electron Positron Collider, more than 100 thousand $J/\psi \to p \pi^- \bar n + c.c.$ events are obtained. Besides two well known $N^*$ peaks at 1500 MeV 1670 MeV, there new, clear $p\pi$ invariant mass spectrum around 1360 2030 MeV....
Abstract Background Radiotherapy is a primary therapeutic modality for esophageal squamous cell carcinoma (ESCC), but its effectiveness still restricted due to the resistance of cancer cells radiation. Long non‐coding RNAs (lncRNAs) and N 6 ‐methyladenosine (m6A) have been shown play significant roles in tumour radioresistance. However, precise manifestation role m6A‐modified lncRNAs ESCC radioresistance remain unclear. Methods Bioinformatics analysis was conducted identify implicated ESCC....
