and Seesaw Dirac Neutrinos
Ernest Ma
In the context of , it is shown how seesaw Dirac neutrinos may be obtained. In this framework, lepton number is conserved, with which self-in…
, Seesaw Dark Matter, and Higgs Decay
Ernest Ma
It has recently been pointed out that the underlying symmetry of dark matter may well be (coming from ) with the dark parity of any given p…
as the Origin of Dark Matter
Ernest Ma
In the decomposition of grand unification to , two desirable features are obtained with the addition of one colored fermion octet , one electroweak…
Baryon-Lepton Duplicity as the Progenitor of Long-Lived Dark Matter
Ernest Ma
In an extension of the standard model, it is shown how the neutral fermion in the doublet may be assigned baryon number , in contrast to its …
Flavor Changing Neutral Currents in the Asymmetric Left-Right Gauge Model
Chia-Feng Chang, Ernest Ma
In the extension of the standard model, a minimal (but asymmetric) scalar sector consists of one $SU(2)_R \times U(1)_…
Syndetic Extension of Baryon and Lepton Numbers: Proton Decay and Long-Lived Dark Matter
Ernest Ma, Koji Tsumura
The well-known baryon and lepton numbers of the standard model of quarks and leptons are extended to include new fermions and bosons in a simple structure with several essential fe…
