A note on Majorana neutrinos, leptonic CKM and electron electric dipole moment
Daniel Ng, John N. Ng
The electric dipole moment of the electron, , is known to vanish up to thre e-loops in the standard model with massless neutrinos. However, if neutrinos are massive Majorana p…
The Excess and Top Decay
Ernest Ma, Daniel Ng
The apparent excess of events at LEP may be an indication of new physics beyond the standard model. However, in either the two-Higgs-doublet model or the m…
The Excess at LEP: Clue to New Physics at the TEVATRON?
Ernest Ma, Daniel Ng
If the excess at LEP is real, then any explanation in terms of renormalizable loop corrections leads to important new decay modes of the quark and suppresses the $t \to b…
What can we learn from the measurement ?
Daniel Ng
We examine the effect of new physics on the . Conditions for large contributions are derived.
Muon Number Violating Processes in Single Particle Extensions of the Standard Model
Daniel Ng, John N. Ng
We study the one-loop induced muon number processes when the standard model is minimally extended to include a singlet of a charged scalar and a neutral fermion $…
Phenomenological Consequences of Singlet Neutrinos
Lay Nam Chang, Daniel Ng, John N. Ng
In this paper, we study the phenomenology of right-handed neutrino isosinglets. We consider the general situation where the neutrino masses are not necessarily given by ,…
Can -- Conversion in Nuclei be a Good Probe for Lepton-Number Violating Higgs Couplings ?
Daniel Ng, John Ng
Motivated by the improving sensitivity, , of experiments on and the enhanced Higgs nucleon interaction, we study this lepton number violating process ind…
SSC Phenomenology of the 331 Model of Flavor
Paul H. Frampton, James T. Liu, Daniel Ng +1
The 331 model offers an explanation of flavor by anomaly cancellation between three families. It predicts three exotic quarks, , , , and five extra gauge bosons comprisi…
The electroweak theory of SU(3) U(1)
Daniel Ng
An electroweak model of SU(3) U(1) gauge group is studied. {}From the group theoretical constraint, the symmetry breaking of this model to the standard model occurs at 1.7…
Search for Dileptons in Z decay
P. H. Frampton, Daniel Ng, T. W. Kephart +1
The lepton family number violation boson decay, or , mediated by a dilepton, e.g. from an SU(15) theory, is calculated. The branching ratio o…
Search for Heavy Leptons at Hadron Colliders
Paul H. Frampton, Daniel Ng, Marc Sher +1
Four models are considered which contain heavy leptons beyond the three families of the standard model. Two are fourth-generation extensions of the standard model in which the righ…
Phenomenological Aspects of Supersymmetric Standard Models without Grand Unification
Satoshi Mizuta, Daniel Ng, Masahiro Yamaguchi
When the GUT relation on gaugino masses is relaxed, the mass and composition of the lightest neutralino are different from those in the GUT case. We discuss its phenomenological im…
QCD renormalization for the top-quark mass in a mass geometrical mean hierarchy
Daniel Ng
renormalization for the top-quark mass is calculated in a mass geometrical mean hierarchy, and . The physical mass, $m_t(m_t) = 160 {\pm} 5…
