Phys. Lett. B Phys. Lett. B Quasinormal modes of Reissner-Nordström Anti-de Sitter Black Holes Wang B Lin C Y Abdalla Elcio 2000 481 79 88 Complex frequencies associated with quasinormal modes for large Reissner-Nordstr$\ddot{o}$m Anti-de Sitter black holes have been computed. These frequencies have close relation to the black hole charge and do not linearly scale with the black hole temperature as in Schwarzschild Anti-de Sitter case. In terms of AdS/CFT correspondence, we found that the bigger the black hole charge is, the quicker for the approach to thermal equilibrium in the CFT. The properties of quasinormal modes for $l>0$ have also been studied. research-article

HyperCP: A high-rate spectrometer for the study of charged hyperon and kaon decays Burnstein R A Chakravorty A Chan A Chen Y C Choong W S Clark K Dukes E C Durandet C Félix J Fuzesy R Z Gidal G Gu P Gustafson H R Ho C Holmstrom T Huang M James C Jenkins C M Jones T D Kaplan D M Lederman Leon Max Leros Nicolas Longo M J López F Lu L C Luebke W Luk K B Nelson K S Park H K Perroud Jean-Pierre Rajaram D Rubin H A Teng P K Turko B T Volk J White C G White S L Zyla Piotr 2004 The HyperCP experiment (Fermilab E871) was designed to search for rare phenomena in the decays of charged strange particles, in particular CP violation in $\Xi$ and $\Lambda$ hyperon decays with a sensitivity of $10^{-4}$. Intense charged secondary beams were produced by 800 GeV/c protons and momentum-selected by a magnetic channel. Decay products were detected in a large-acceptance, high-rate magnetic spectrometer using multiwire proportional chambers, trigger hodoscopes, a hadronic calorimeter, and a muon-detection system. Nearly identical acceptances and efficiencies for hyperons and antihyperons decaying within an evacuated volume were achieved by reversing the polarities of the channel and spectrometer magnets. A high-rate data-acquisition system enabled 231 billion events to be recorded in twelve months of data-taking. PREPRINT
