Horizontal Symmetries and Flavor Mixings in Left-Right Symmetric Models*
AbstractWe review the prospects for calculating flavor mixings in weak interactions using continuous or discrete Horizontal symmetries. A model obtained by imposing Z4 symmetry on an SU(2)L x SU(2)R x...
View ArticleLeft-Right Symmetric Models of Weak Interactions: A Review
AbstractThe last ten years has seen a revolution of sorts in our understanding of the weak interaction phenomena. The four-fermion V-A theory suggested in 1957 by Sudarshan, Marshak, Feynman, Gell-Mann...
View ArticleLocal Supersymmetry (N = 1)
AbstractIn this chapter we will study the implications of the hypothesis that the parameters of supersymmetry transformation ε become a function of space-time, i.e., ε = ε(x). We know, from Chapter 1,...

AbstractOne of the original motivations for the application of supersymmetry to particle physics was to solve the gauge hierarchy problem that arises in the grand unification program. As has been...

AbstractIn this section we will apply the ideas of spontaneously broken gauge theories to construct the first successful model of electro-weak interaction of quarks and leptons. As we discussed in the...
View ArticleCP-Violation: Weak and Strong
AbstractThe phenomenon of CP-violation was discovered in 1964 by Christenson, Cronin, Fitch, and Turlay in K0-decays. To date Kaon systems have remained the only place where breakdown of CP-invariance...

AbstractWe study the thermal properties and the thermodynamical equilibrium fluctuations of a gas of massive heterotic string excitations at Planck energy scales. The behavior of this system parallels...

AbstractIn the previous chapters we have emphasized that while the success of the SU(2) L× U(1)Y× SU(3)C model has indicated that the unified gauge theories are perhaps the right theoretical framework...

AbstractRare muon processes such as muonium to antimuonium conversion, μ→ eγ and μ→ 3e provide sensitive tests of new physics beyond the standard model. Specifically the left-right symmetric models of...

AbstractWe consider chiral symmetry breaking through nontrivial vacuum structure with an explicit construct for the vacuum with quark antiquark condensates in QCD with Coulomb gauge for different...
View ArticleTheories of Neutrino Masses and Mixings
AbstractThe history of weak-interaction physics has to a large extent been a history of our understanding of the properties of the elusive spin-half particles called neutrinos. Evidence for only...

AbstractIn a class of extensions of the minimal supersymmetric standard model with (B-L)/left-right symmetry that explains the neutrino masses, breaking R-parity symmetry is an essential and dynamical...
View ArticleGauged flavor group with left-right symmetry
AbstractWe construct an anomaly-free extension of the left-right symmetric model, where the maximal flavor group is gauged and anomaly cancellation is guaranteed by adding new vectorlike fermion...
View ArticleA naturally light sterile neutrino in an asymmetric dark matter model
AbstractA recently proposed asymmetric mirror dark matter model where the mirror sector is connected with the visible one by a right-handed neutrino portal, is shown to lead naturally to a 3+1...
View ArticleTeV scale universal seesaw, vacuum stability and heavy Higgs
AbstractWe discuss the issue of vacuum stability of standard model by embedding it within the TeV scale left-right universal seesaw model (called SLRM in the text). This model has only two coupling...
