Diagonal elements of symmetric matrix
WebThe extension of the Standard model by three right-handed neutrino fields exhibit appealing symmetry between left-handed and right-handed sectors, which is only violated by interactions. It can accommodate three flavor quasi-Dirac neutrino mixing scheme, which allows processes with violation of both lepton flavor and total lepton number symmetries. … WebIn a scalar matrix, all off-diagonal elements are equal to zero and all on-diagonal elements happen to be equal. In other words, we can say that a scalar matrix is an identity matrix’s multiple. ... This is because its …
