Intrinsic flavor violation for massive neutrinos
C. C. Nishi
It is shown that intrinsic neutrino flavor violation invariably occurs when neutrinos are created within the SM augmented by the known massive neutrinos, with mixing and nondegener…
Absolute neutrino mass from helicity measurements
C. C. Nishi
The possibility to access the absolute neutrino mass scale through the measurement of the wrong helicity contribution of charged leptons is investigated in pion decay. Through this…
Flavor mixing in a Lee-type model
C. C. Nishi, M. M. Guzzo
An exactly solvable Quantum Field Theory (QFT) model of Lee-type is constructed to study how neutrino flavor eigenstates are created through interactions and how the localization p…
Physical parameters and basis transformations in the Two-Higgs-Doublet model
C. C. Nishi
A direct connection between physical parameters of general Two-Higgs-Doublet Model (2HDM) potentials after electroweak symmetry breaking (EWSB) and the parameters that define the p…
Structure of potentials with Higgs doublets
Celso C. Nishi
Extensions of the Standard Model with Higgs doublets are simple extensions presenting a rich mathematical structure. An underlying Minkowski structure emerges from the study of…
Simple derivation of general Fierz-type identities
C. C. Nishi
General Fierz-type identities are examined and their well known connection with completeness relations in matrix vector spaces is shown. In particular, I derive the chiral Fierz id…
