On the Behavior of the Effective QCD Coupling alpha_tau(s) at Low Scales
Stanley J. Brodsky, Sven Menke, Carlos Merino +1
The hadronic decays of the tau lepton can be used to determine the effective charge alpha_tau(m^2_tau') for a hypothetical tau-lepton with mass in the range 0 < m_tau' < m_tau. Thi…

The ROSAT Deep Survey IV. A distant lensing cluster of galaxies with a bright arc
G. Hasinger, R. Giacconi, J. E. Gunn +7
An unusual double-lobed extended X-ray source (RX J105343+5735) is detected in the ROSAT ultra-deep HRI image of the Lockman Hole. The angular size of the source is 1.7 X 0.7 arcmi…
