AbstractAbstract
[en] It is assumed that three lepton families (νe,e), (νμ, μ), (ντ, τ) carry charges, which are sources of electronic, muonic and tauonic massless vector particles (photons), respectively. Various manifestations of these hypothetical photons are discussed. (author)

AbstractAbstract
[en] Lepton number violation and its relation to neutrino masses are investigated in several versions of the SU(3)_c⊗SU(3)_L⊗U(1)_x model. Spontaneous and explicit violation and conservation of the lepton number are considered. In one of the models (the so-called economical one), the lepton number is spontaneously violated and it is found that the would be Majoron is not present because it is gauged away, providing in this way the longitudinal polarization component to a now massive gauge field

AbstractAbstract
[en] We consider a left-right symmetric model with three generations and with the standard assignments of fermion and scalar fields. The left-right symmetry gives rise to a unique conserved lepton number which is of the Zel'dovich-Konopinski-Mahmoud type. The neutrino mass matrix yields one Dirac and one Majorana neutrino, both in the light and in the heavy sector. Up to small mixings with right-handed neutrinos, the left-handed νsub(e) and νsub(tau) combine to the light Dirac neutrino whereas νsub(μ) is the light Majorana neutrino. With a right-handed scale in the TeV range all light neutrino masses can naturally be of the order of several eV despite the large hierarchy in the charged lepton masses. Phenomenological consequences of the model are discussed. (Author)

AbstractAbstract
[en] If one imposes the permutation symmetry Ssub(n) (n is the number of lepton flavours) reducibly on the different families (e, μ, tau, ...), it follows that at least two leptons have the same mass if n > 6. If equal lepton masses are excluded, this implies a bound on the number of flavours

AbstractAbstract
[en] The authors examine a mechanism which can lead to flavor transformation of neutrino-antineutrino asymmetries in the early universe, a process which is unavoidable when the neutrino mixing angles are large. This sets the best limit on the lepton number of the universe, and hence on the relic neutrino abundance. They also consider the consequences for the relic neutrino abundance if extra neutrino interactions are allowed, e.g., the coupling of the neutrinos to a light (compared to mv) boson. For a wide range of couplings not excluded by other considerations, the relic neutrinos would annihilate to bosons at late times, and thus make a negligible contribution to the matter density today. This mechanism evades the neutrino mass limits arising from large scale structure
