Using the upgraded Beijing Spectrometer, we have measured total cross section for e+e− annihilation into hadronic final states at center-of-mass energies of 2.6, 3.2, 3.4, 3.55, 4.6, and 5.0 GeV. Values R, σ(e+e−→hadrons)/σ(e+e−→μ+μ−), are determined.Received 28 July 1999DOI:https://doi.org/10.1103/PhysRevLett.84.594©2000 American Physical Society
Metal atom doping, an easy and convenient method, can optimize tune the physical-chemical properties photometrics of carbon dots (CDs). However, there are few reports on preparation metal-decorated CDs that give red emission a high photoluminescence quantum yield (PLQY). Here, we demonstrate zinc (existing in human body) ion-doping strategy to observably enhance PLQY lengthen CD wavelength. The prepared Zn/ZnO-decorated (Zn-CDs) produced fluorescence (623 nm) with superior 40.3%. Through...
Hadronic decays of the P-wave spin-triplet charmonium states χcJ(J=0,1,2) are studied using a sample ψ(2S) collected by BES detector operating at BEPC storage ring. Branching fractions for χc1→K0SK+π−+c.c., χc0→K0SK0S, χc2→K0SK0S, χc0→φφ, χc2→φφ and χcJ→K+K−K+K− measured first time, those χcJ→π+π−π+π−, χcJ→π+π−K+K−, χcJ→π+π−p¯p χcJ→3(π+π−) with improved precision.

The data on $J/\ensuremath{\psi}\ensuremath{\rightarrow}\ensuremath{\gamma}{K}^{+}{K}^{\ensuremath{-}}$ from the BES experiment at Beijing electron-positron collider have been analyzed. We find two resonances in 1.7 GeV region which were identified as ${f}_{J}(1710)$: a scalar with mass $1781\ifmmode\pm\else\textpm\fi{}{8}_{\ensuremath{-}31}^{+10}(\mathrm{MeV})$ and width $85\ifmmode\pm\else\textpm\fi{}{24}_{\ensuremath{-}19}^{+22}(\mathrm{MeV})$, tensor...
Let T=(RM0S) be a triangular matrix ring with R and S rings RMS an R–S-bimodule. We describe Gorenstein projective modules over T. In particular, we refine result of Enochs, Cortés-Izurdiaga, Torrecillas [Gorenstein conditions rings, J. Pure Appl. Algebra 218 (2014), no. 8, 1544-1554]. Also, consider when the recollement Db(T‐Mod) restricts to its subcategory Db(T‐Mod)fgp consisting complexes finite dimension. As applications, obtain recollements stable category T‐GProj¯ defect Ddef(T‐Mod).
In order to address the challenges associated with optimizing multi-timescale operations and allocating ultra-short-term energy storage for HWP integration, this study takes into account both economic reliability aspects of integration base. It proposes a model capacity, achieving optimization across long-term, short-term, an MECB. Initially, operation is implemented entire group terraced hydropower plants by regulating them annual capabilities on long-term timescale. The objectives are...

This model, which written in terms parameter κ, predicts pions should be present. determine...
To investigate cohomology theories based on flats, Asadollahi and Salarian gave the definition of F-Gorenstein flat R-modules, these modules are exactly Gorenstein provided that R is right coherent. In this paper, we get some properties R-modules establish stability categories.
A comparison of the rates for ψ(2S)→π+π−J/ψ, J/ψ→l+l− and J/ψ→ anything is used to determine J/ψ leptonic branching fractions. The results are B(J/ψ→e+e−)=(5.90±0.05±0.10)% B(J/ψ→μ+μ−)=(5.84±0.06±0.10)%, where first error statistical second systematic.

The decays of the $\ensuremath{\psi}(2S)$ into vector plus tensor meson final states have been studied for first time using BES detector. We determine upper limits on branching fractions $\ensuremath{\omega}{f}_{2}$, $\ensuremath{\rho}{a}_{2}$, ${K}^{*0}{\overline{K}}_{2}^{*0}+\mathrm{c}.\mathrm{c}.$, and $\ensuremath{\varphi}{f}_{2}^{\ensuremath{'}}(1525)$ that are, in each case, significantly smaller than corresponding $J/\ensuremath{\psi}$ meson, scaled according to expectations perturbative QCD.

Radiative decays of the radially excited charmonium resonance, \psi(2S), into \pi\pi, K Kbar and \eta\eta final states have been measured in a sample 3.96 * 10^6 \psi(2S) events collected by BES collaboration.
