Lepton Charges in Current Descriptions of Weak Processes

Аннотация

A family of leptons based on charged \({{l}_{{{\text{ch}}}}}\) and neutral (neutrino) \({{l}_{\nu }}\) quantum numbers is described while retaining their sum \({{L}_{{{\text{ch}}}}}\) and total aroma \({{L}_{\nu }}.\) Representations of a four-component neutrino theory are expanded by including a tauon family and a new (fourth) lepton family. (Non)diagonal lepton processes are studied with respect to the interaction between neutral (NC) and charged (CC) weak currents. It is shown that information on current constants can be obtained by measuring the recoil electron spectra and total cross sections of elastic \(\nu e\) and \(\tilde {\nu }e\) types of scattering.
