We also find that if the W R is light, the cross section for production of W L −W R − could be measurable even for even small neutrino mixing. We point out that good charged lepton identificationis essential to distinguish the signal from background....

lepton- an elementary particle that participates in weak interactions; has a baryon number of 0 photoelectron- an electron that is emitted from an atom or molecule by an incident photon valence electron- an electron in the outer shell of an atom which can combine with other atoms to form mole...
In this frame the e+ and neutrino are moving in opposite directions. The helicity of the neutrino is equal to −1. If we neglect the mass of the positron the helicity of the positron will be the same as the helicity of the antineutrino and it will be equal to +1. Thus, the ...
Since the discovery of neutrino oscillations, we know that neutrinos have non-zero mass. However, the absolute neutrino-mass scale remains unknown. Here we report the upper limits on effective electron anti-neutrino mass, mν, from the second physics run
We find that the inclusion of neutrino-electron scattering approximately doubles the emitted neutrino flux during infall. Neutrino-electron scattering increases the rate at which energy and lepton number are transferred from the matter to the neutrinos. However, the transfer of entropy to the matter ...

We examine single chargino production in conjunction with R-parity leptonnumber violation in future lepton-lepton collisions. Present bounds on R-parityviolating couplings allow for a production cross section of the order of${\\cal{O}} (10 {fb})$ for a wide range of sneutrino and chargino...
A realistic scheme for masses and mixing of leptons is investigated in themodel with gauged SO(3) lepton flavor symmetry. Within this scheme, a nearly`bi-m... YL Wu - 《European Physical Journal C》 被引量: 47发表: 1999年 Non-oscillation searches of neutrino mass in the age of oscillat...
Observed reactions always conserve lepton numbers, while reactions which violate lepton number conservation are “forbidden” and are never observed. For example, the neutrino scattering reaction νμ+n→μ−+p is observed experimentally, while the apparently similar reaction νμ+n→e−+p which ...
