Generalized Super-v{C}erenkov Radiations (Sv{C}R), as well as their Sv{C}R-signatures are investigated. Two general Sv{C}R-coherence conditions are found as two natural extremes of the same spontaneous particles decays in (dielectric, nuclear or hadronic) media. The main results on the experimental test of the super-coherence conditions, obtained by using the experimental data from BNL, are presented. The interpretation of the observed anomalous v{C}erenkov rings as experimental evidence for the HE-component of the Sv{C}R is discussed.
Generalized mesonic Super-v{C}erenkov Radiations (Sv{C}R) are investigated. The energy behavior of the pionic refractive index in the low energy pionic SCR-sector is presented. We estimated that the true coherent SCR-pion emission is possible mainly
CANGAROO group has constructed the new large imaging Air v Cerenkov telescope to exploit hundred GeV region gamma-ray astronomy in March 1999 at Woomera, South Australia. It has a 7m parabolic mirror consisting of 60 small plastic spherical mirrors,
The shape of the beta decay energy distribution is sensitive to the mass of the electron neutrino. Attempts to measure the endpoint shape of tritium decay have so far seen no distortion from the zero-mass form, thus placing an upper limit of m_nu_bet
Pachmarhi Array of v{C}erenkov Telescopes (PACT), based on wavefront sampling technique, has been used for detecting TeV gamma rays from galactic and extra-galactic $gamma $-ray sources. The Blazar, Mkn 421 was one such extra-galactic source observed
A new search for the decay modes of the 4-fold forbidden non-unique decay of $^{50}$V has been performed at the Gran Sasso Underground Laboratory (LNGS). In total an exposure of 197 kg $times$ d has been accumulated. The half-life for the electron ca
