We discuss the possibility of testing the Majorana nature of the neutrino in electron-electron colliders. We consider the reaction e − e − → W − W −, where the W is either left- or right-handed. We find that for the production of standard W's, a collider with s ⩾ 1...

In the presence of rapid fermion-number violation due to nonperturbative electroweak effects certain relations between the baryon number of the Universe and the lepton numbers of the Universe are predicted. In some cases the electron-neutrino asymmetry is exactly specified in terms of the baryon asym...
Lepton (lĕp′tŏn″) [Gr.,=light (i.e., lightweight)], class of elementary particles that includes the electron and its antiparticle, the muon and its antiparticle, the tau and its antiparticle, and the neutrino and antineutrino associated with each of these particles. Leptons are the...
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...
Besides, either if we choose an electron pair or a muon pair to reconstruct the Z boson, leptons decaying from the Higgs boson and from the Z boson may get mixed up. Of course, one can always combine the analyses based on all the possible methods of reconstructing the Z boson to ...
any of a class of particles with spin of ½ that are not subject to the strong force and that are believed to be truly elementary and not composed of quarks or other subunits. The leptons known or believed to exist are the electron and electron-neutrino, the muon and mu-neutrino, and...
