Political Policing in Hong Kong

Modem states, democratic ones in particular, have grown to prefer the use of more subtle, or at least less visible, police surveillance to open confrontation in a courtroom, where the state itself may be scrutinised in public. Well-equipped national security agencies enable the state to respond to potential security threats before they mature. Hong Kong's political police unit, the Special Branch, was indispensable to Hong Kong's colonial political order. Although it was disbanded before the handover of Hong Kong to China in 1997, political policing and monitoring probably continue under the new legal order. This article examines the historical origin of political policing in Hong Kong, including the establishment of the Special Branch and its initial focus on communist activity in Hong Kong. It then traces the demise of the Special Branch prior to the handover, examines the role played by the Independent Commission Against Corruption, and explores the relevance of political policing to contemporary society.published_or_final_versio

First observation of psi(2S)-->K_S K_L

The decay psi(2S)-->K_S K_L is observed for the first time using psi(2S) data collected with the Beijing Spectrometer (BESII) at the Beijing Electron Positron Collider (BEPC); the branching ratio is determined to be B(psi(2S)-->K_S K_L) = (5.24\pm 0.47 \pm 0.48)\times 10^{-5}. Compared with J/psi-->K_S K_L, the psi(2S) branching ratio is enhanced relative to the prediction of the perturbative QCD ``12%'' rule. The result, together with the branching ratios of psi(2S) decays to other pseudoscalar meson pairs (\pi^+\pi^- and K^+K^-), is used to investigate the relative phase between the three-gluon and the one-photon annihilation amplitudes of psi(2S) decays.Comment: 5 pages, 4 figures, 2 tables, submitted to Phys.

Study of psi(2S) decays to X J/psi

Using J/psi -> mu^+ mu^- decays from a sample of approximately 4 million psi(2S) events collected with the BESI detector, the branching fractions of psi(2S) -> eta J/psi, pi^0 pi^0 J/psi, and anything J/psi normalized to that of psi(2S) -> pi^+ pi^- J/psi are measured. The results are B(psi(2S) -> eta J/psi)/B(psi(2S) -> pi^+ pi^- J/psi) = 0.098 \pm 0.005 \pm 0.010, B(psi(2S) -> pi^0 pi^0 J/psi)/B(psi(2S) -> pi^+ pi^- J/psi) = 0.570 \pm 0.009 \pm 0.026, and B(psi(2S) -> anything J/psi)/B(psi(2S) -> pi^+ pi^- J/psi) = 1.867 \pm 0.026 \pm 0.055.Comment: 13 pages, 8 figure
