Candidates for dark matter in the models
H. N. long, N. Q. Lan, D. V. Soa +1
It has recently been pointed out that the 511 keV emission line detected by INTEGRAL/SPI from the bulge of our galaxy could be explained by annihilations of light dark matter parti…
Photon - Axion Conversion Cross Sections in a Resonant Cavity
Dang Van Soa, Hoang Ngoc Long, Le Nhu Thuc
Photon - axion conversions in the resonant cavity with the lowest mode are considered in detail by the Feynman diagram method. The differential cross sections are presented and num…
Neutrino masses in the economical 3-3-1 model
P. V. Dong, H. N. Long, D. V. Soa
We show that, in frameworks of the economical 3-3-1 model, the suitable pattern of neutrino masses arises from the three quite different sources - the lepton-number conserving, the…
Fermion masses in the economical 3-3-1 model
P. V. Dong, D. T. Huong, Tr. T. Huong +1
We show that, in frameworks of the economical 3-3-1 model, all fermions get masses. At the tree level, one up-quark and two down-quarks are massless, but the one-loop corrections g…
Neutrino Masses in the Supersymmetric SU(3)_C X SU(3)_L X U(1)_X Model with right-handed neutrinos
P. V. Dong, D. T. Huong, M. C. Rodriguez +1
The R-symmetry formalism is applied for the supersymmetric SU(3)_C X SU(3)_L X U(1)_X (3-3-1) model with right-handed neutrinos. For this kind of models, we study generalization of…
Atomic parity violation in the economical 3-3-1 model
P. V. Dong, H. N. Long, D. T. Nhung
The deviation $\de Q_{\mathrm{W}}$ of the weak charge from its standard model prediction due to the mixing of the boson with the charged bilepton as well as of the boso…
Higgs-gauge boson interactions in the economical 3-3-1 model
Phung Van Dong, Hoang Ngoc Long, Dang Van Soa
Interactions among the standard model gauge bosons and scalar fields in the framework of SU(3)_C X SU(3)_L X U(1)_X gauge model with minimal (economical) Higgs content are presente…
Interesting radiative patterns of neutrino mass in an SU(3)_C X SU(3)_L X U(1)_X model with right-handed neutrinos
Darwin Chang, Hoang Ngoc Long
We investigate a simple model of neutrino mass based on SU(3)_C X SU(3)_L X U(1)_X gauge unification. The Yukawa coupling of the model has automatic lepton-number symmetry which is…
SU(3)_C X SU(3)_L X U(1)_X model with two Higgs triplets
P. V. Dong, H. N. Long, D. T. Nhung +1
The gauge model with the minimal scalar sector (two Higgs triplets) is studied in detail. One of the vacuum expectation values is a source of lepto…
