New Scientist;9/7/91, Vol. 131 Issue 1785, p28
Reports on the theory of American physicist Myron Bander of the University of California, Irvine that a fourth neutrino can exist without upsetting physics and astronomy. Mass and short decay time for such a neutrino; Decay time already postulated by particle physicists for other reasons.

    The beta-neutrino angular correlation coefficient provides a sensitive observable to search for physics beyond the standard electroweak model in nuclear beta decay. We address here the measurement of this parameter in the pure Gamow-Teller transition of 6He. A deviation from the standard model...

    The goal of the Majorana project is to provide limits on the effective neutrino mass at the level of 50 meV through measurements of neutrinoless double beta-decay in 76Ge. The planned experiment relies entirely on proven technology and uses materials and techniques demonstrated to produce the...

    Future nuclear decay experiments have to be able to combine a large mass, the capability of distinguishing between several possible decay channels and a good background discrimination, in order to increase their sensitivity linearly with the mass. We present the capabilities of the liquid Argon...

    Within the quasiparticle random phase approximation (QRPA), the covariances associated to the nuclear matrix elements (NME) of neutrinoless double beta decay (0vββ) are estimated. It is shown that correlated NME uncertainties play an important role in the comparison of 0vββ decay...
