The NA48 experiment at CERN has performed a new measurement of direct CP violation, based on data taken in 1997 by simultaneously collecting K L and K S decays into π 0 π 0 and π + π − . The result for the CP violating parameter Re(ε′/ε) is (18.5±4.5(stat)±5.8(syst))×10 −4 .
A first deep underwater detector for muons and neutrinos, NT-200, is currently under construction in Lake Baikal. Part of the detector, NT-36, with 36 photomultiplier tubes at three strings, has been installed in 1993. This array allowed for the first time a three-dimensional mapping of Cherenkov light deep underwater. Since then, various arrays have been almost continuously taking data. Presently...
