Tracing Metal Sources of Geogas with Lead Isotopes: A Case Study on the Bairendaba Silver‐polymetallic Deposit, Inner Mongolia

Libo Zuo, Wei Wan, Mingqi Wang, F. Z. Qi et autres

Abstract Geogas survey is an unconventional geochemical prospecting method that has proven particularly effective in exploring concealed ore deposits. However, its application in covered areas has been questioned due to the lack of a confirmed geogas formation mechanism. Investigating the sources of …

Spatial equity and factors that influence the distribution of elderly care institutions in China

Xiaohan Li, Weishan Qin, Hongqiang Jiang, F. Z. Qi

BACKGROUND: With China becoming an aging society, the number of elderly care institutions (ECIs) is continuously increasing in response to the growing population of older persons. However, regional disparities may lead to an uneven distribution of ECIs, which could affect equity in …

Study of $Λ_c^+\rightarrow Λμ^+ν_μ$ and Test of Lepton Flavor Universality with $Λ_c^+\rightarrow Λ\ell^+ν_{\ell}$ Decays

BESIII Collaboration, M. N. Achasov, P. Adlarson, X. C. Ai et autres

The measurement of the Cabibbo-favored semileptonic decay $Λ_c^+\rightarrow Λμ^+ν_μ$ is reported using $4.5~\mathrm{fb}^{-1}$ of $e^+e^-$ annihilation data collected at center-of-mass energies ranging from 4.600~GeV to 4.699~GeV. The branching fraction of the decay is measured to be $\mathcal{B}(Λ_c^+\rightarrow Λμ^+ν_μ)=(3.48\pm0.14_{\rm stat.}\pm0.10_{\rm syst.})\%$, three times …

Study of $η(1405)/η(1475)$ in $J/ψ\toγK^{0}_{S} K^{0}_{S}π^{0}$ decay

BESIII Collaboration, М. Н. Ачасов, P. Adlarson, M. Albrecht et autres

Using a sample of $(10.09\pm0.04)\times10^{9}$ $J/ψ$ decays collected with the BESIII detector, partial wave analyses of the decay $J/ψ\toγK^{0}_{S} K^{0}_{S}π^{0}$ are performed within the $K^{0}_{S}K^{0}_{S}π^{0}$ invariant mass region below $1.6\mathrm{\ Ge\kern -0.1em V}/c^2$. The covariant tensor amplitude method is used in both …
