The BES experiment at the Beijing electron-positron collider has observed ξ(2230) signal in π+π−, K+K−, K0SK0S, and p¯p final states with 4.6σ, 4.1σ, 4.0σ, 3.8σ statistical significances, respectively. new observations of two nonstrange decay modes ξ→π+π− are important evidence for glueball interpretation ξ(2230).Received 30 October 1995DOI:https://doi.org/10.1103/PhysRevLett.76.3502©1996 American Physical Society
Twisted 2D transition metal dichalcogenides (TMDCs) play a significant role in the development of twistronics. However, it is still challenging to prepare high-quality twisted TMDCs by current stacking or folding techniques. Herein, we propose cross-domain chemical vapor deposition method synthesize bilayer MoS2 through precisely controlling supply molybdenum precursor. It found that top layer grain maintains its original orientation even when crosses over neighboring monolayer grain. This...
The processes $\ensuremath{\psi}(2S)\ensuremath{\rightarrow}\ensuremath{\gamma}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, $\ensuremath{\gamma}{K}^{+}{K}^{\ensuremath{-}}$, and $\ensuremath{\gamma}p\overline{p}$ have been studied using a sample of $3.79\ifmmode\times\else\texttimes\fi{}{10}^{6}\ensuremath{\psi}(2S)$ decays. We determine the total width ${\ensuremath{\chi}}_{c0}$ to be...
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...
The decay J/ψ→γπ0π0 is studied with 7.0×106J/ψ events collected in the neutral trigger mode by Beijing Spectrometer at Electron-Positron Collider. Evidence for existence of fJ(1710) and ξ(2230) this channel presented, corresponding masses as well product branching ratios are obtained. An interpretation a glueball favored.Received 4 March 1998DOI:https://doi.org/10.1103/PhysRevLett.81.1179©1998 American Physical Society
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. Assuming lepton universality, fraction B(J/ψ→l+l−)=(5.87±0.04±0.09)% per species. This result estimate QCD scale factor ΛMS¯(4) strong coupling constant αs.

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.
We report first measurements of the branching fractions B(ψ2S→γη′)=(1.54±0.31±0.20)×10−4 and B(ψ2S→γη)=(0.53±0.31±0.08)×10−4. The ψ(2S)→γη′ result is consistent with expectations a model that considers possibility η′−ηc(2S) mixing. ratio ψ(2S)→γη rates used to determine pseudoscalar octet-singlet mixing angle.Received 5 February 1998DOI:https://doi.org/10.1103/PhysRevD.58.097101©1998 American Physical Society
A search is performed for the production of ψ(2S) in e+e− annihilation at a center-of-mass energy 4.03 GeV using BES detector operated Beijing Electron Positron Collider (BEPC). The kinematic features reconstructed signal are consistent with its being produced only association an energetic photon resulting from initial state radiation (ISR). Limits placed on decay unknown charmonia or metastable hybrids that might be annihilations GeV. Under assumption observed cross section due entirely to...
Monolayer molybdenum disulfide (MoS2), a typical transition metal dichalcogenide (TMD), is promising functional material for next-generation electronics. However, growing large-domain-sized MoS2 single crystals on SiO2 remains considerably challenging. The amorphous structure and lack of catalytic activity prevent the deposition high-quality monolayer MoS2. Herein, Na-assisted space-confining method deployed to directly synthesize single-crystal SiO2. domain size reaches 450 μm within 3 min,...
