A New Type of Resonant Neutrino Conversions Induced by Magnetic Fields
S. Sahu, V. B. Semikoz, J. W. F. Valle
We consider resonant neutrino conversions in magnetised matter, such as a degenerate electron gas. We show how magnetisation effects caused by axial vector interactions of neutrino…
Looking for Invisibly Decaying Higgs Bosons through the Final State $b\bar{b}+\protect\ptmis$
Oscar J. P. Eboli, F. de Campos, J. Rosiek +1
We study the potential of LEP II to unravel the existence of invisibly decaying Higgs bosons through the reaction $e^+ e^- \rightarrow b\bar{b} + \ptmis$. We perform our analyses i…
Neutrino-less Double Beta Decay and Physics Beyond the Standard Model
Jose W. F. Valle
A brief sketch is given of the present observational status and future prospects of the physics of neutrino mass, including a survey of the various theoretical schemes of neutrino…
Dynamical Left-Right Symmetry Breaking
E. Akhmedov, M. Lindner, E. Schnapka +1
We study a left--right symmetric model which contains only elementary gauge boson and fermion fields and no scalars. The phenomenologically required symmetry breaking emerges dynam…
Left-Right Symmetry Breaking in NJL Approach
E. Akhmedov, M. Lindner, E. Schnapka +1
We study left-right symmetric models which contain only fermion and gauge boson fields and no elementary scalars. The Higgs bosons are generated dynamically through a set of gauge-…
Structure Formation with a Decaying Mev Tau Neutrino and a Kev Majoron
A. D. Dolgov, S. Pastor, J. W. F. Valle
We consider the scenario of large scale structure formation with tau neutrino with mass in the MeV range and lifetime of order of years which decays into a massive majoron with KeV…
