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
An enhancement near threshold is observed in the omega(phi) invariant mass spectrum from doubly Okubo-Zweig-Iizuka-suppressed decays of J/psi-->gamma(omega)phi, based on a sample 5.8 x 10(7) J/psi events collected with BESII detector. A partial wave analysis shows that this favors JP=0+, and its width are M=1812(+19)(-26)(stat)+/-18(syst) MeV/c2 Gamma=105+/-20(stat)+/-28(syst) MeV/c2. The product branching fraction determined to be...
The mass of the τ lepton has been measured at Beijing Electron-Positron Collider using Spectrometer. A search near threshold for e+e−→τ+τ− was performed. Candidate events were identified by requiring that one decay via τ→eνν¯, and other τ→μνν¯. value, obtained from a fit to energy dependence τ+τ− cross section, is mτ=1776.9+0.4−0.5±0.2 MeV.Received 7 August 1992DOI:https://doi.org/10.1103/PhysRevLett.69.3021©1992 American Physical Society
Abstract The gate-tunable superconductivity in metallic superconductors has recently attracted significant attention due to its rich physics and potential applications next-generation superconducting electronics. Although the operating principles of these devices have been attributed small leakage currents high-energy electrons recent experiments, generated phonons can spread over considerable distances substrate, which may limit their further applications. Here, we utilize a top gate...
This study explores gate-controlled superconductivity in metallic superconductors by employing a top-gate architecture with 15 nm monocrystalline h-BN as gate dielectric. The transport properties under voltage can be elucidated injecting high-energy electrons, following the Fowler–Nordheim electron field emission model. In contrast to conventional resistive Joule heating, injection top-gating exhibits excellent power efficiency suppressing superconductivity. A nearby superconducting bridge,...
Multimodal large language models (MLLMs) have advanced the integration of visual and linguistic modalities, establishing themselves as dominant paradigm for visual-language tasks. Current approaches like chain thought (CoT) reasoning augmented cognitive capabilities (LLMs), yet their adaptation to MLLMs is hindered by heightened risks hallucination in cross-modality comprehension. In this paper, we find that thinking while looking current multimodal CoT approaches--where chains are generated...
