A Proposal for Rapid Assessment of Long-Distance Oil and Gas Pipelines After Earthquakes

Hongyuan Jing, Liang Huang, H. M. Liu, Weijun Jiang et autres

A substantial proportion of long-distance oil and gas pipelines in China traverse active faults and high-risk areas characterised by intricate topographic and geological environments. These pipelines are susceptible to a range of safety concerns, exacerbated by the increasing frequency of strong earthquakes …

Measurement of the $\boldsymbol{e^{+}e^{-}\to K^+K^-ψ(2S)}$ Cross Section at Center-of-Mass Energies from 4.699 to 4.951 GeV and Search for $\boldsymbol{Z_{cs}^{\pm}}$ in the $\boldsymbol{Z_{cs}^\pm\to K^\pmψ(2S)}$ Decay

BESIII Collaboration, M. Ablikim, Mikhail N. Achasov, P. Adlarson et autres

We perform the first investigation of the process $e^{+}e^{-}\to K^+K^-ψ(2S)$ and report its Born cross sections over a range of center-of-mass energies from 4.699 to 4.951~GeV. The measurements are carried out using several partial reconstruction techniques using data samples collected by the …
