Cross sections and form factors for ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\omega}{\ensuremath{\pi}}^{0}$, $\ensuremath{\rho}\ensuremath{\eta}$, $\ensuremath{\rho}{\ensuremath{\eta}}^{\ensuremath{'}}$ at center of mass energies 3.650, 3.686, 3.773 GeV are measured using data samples collected with the BESII detector BEPC. Also, branching fractions $\ensuremath{\psi}(2S)\ensuremath{\rightarrow}\ensuremath{\omega}{\ensuremath{\pi}}^{0}$, determined to be...
Using photon conversions to e+e− pairs, the energy spectrum of inclusive photons from ψ(2S) radiative decays is measured with resolution (σEγ) in range 2.3 3.8 MeV by BESII at Beijing Electron-Positron Collider. The χcJ(1P) states (J=0,1,2) are clearly observed, and their masses spin-averaged χcJ mass determined be Mχc0=3414.21±0.39±0.27, Mχc1=3510.30±0.14±0.16, Mχc2=3555.70±0.59±0.39, M(Pcog3)=3524.85±0.32±0.30 MeV/c2, respectively.Received 6 February...

Based on 5.8×107J/ψ events detected in BESII, the branching fractions of J/ψ→ϕη and ϕη′ are measured for different η η′ decay modes. The results significantly higher than previous measurements. An upper limit B(J/ψ→ϕπ0) is also obtained.3 MoreReceived 15 October 2004DOI:https://doi.org/10.1103/PhysRevD.71.032003©2005 American Physical Society

In simultaneous-shot full-waveform inversion (FWI), the re-started limited-memory Broyden-Fletcher-Goldfarb-Shanno (L-BFGS) algorithm can be used to suppress crosstalk, but crosstalk cannot completely eliminated from results. To further solve problem caused by interference among individual shots in FWI, adaptive structure-based smoothing is applied FWI with restarted L-BFGS algorithm. Structure-based mitigate highlighting structure boundaries. perform smoothing, an implicit anisotropic...
