Hidden Gauge Symmetry
In the four dimensional free fermionic formulation of the heterotic string, a semi-realistic SU(4) × SU(2) L × SU(2) R model is proposed with three fermion generations in (4, 2, 1) + (¯ 4, 1, 2) representations. The gauge symmetry of the model breaks to the standard gauge group using a higgs pair in the (4, 1, 2)+(¯ 4, 1, 2) representations. The massless spectrum includes exotic fractionally ch...
متن کاملSeesaw Neutrino Mass and New U(1) Gauge Symmetry
The three electroweak doublet neutrinos νe,μ,τ of the Standard Model may acquire small seesaw masses, using either three Majorana fermion singlets N or three Majorana fermion triplets (Σ,Σ,Σ). It is well-known that the former accommodates the U(1) gauge symmetry B−L. It has also been shown some years ago that the latter supports a new U(1)X gauge symmetry. Here we study two variations of this U...
متن کاملGeometric phases and hidden local gauge symmetry
The analysis of geometric phases associated with level crossing is reduced to the familiar diagonalization of the Hamiltonian in the second quantized formulation. A hidden local gauge symmetry, which is associated with the arbitrariness of the phase choice of a complete orthonormal basis set, becomes explicit in this formulation (in particular, in the adiabatic approximation) and specifies phys...
متن کاملMagnetic Charge as a “Hidden” Gauge Symmetry
A theory containing both electric and magnetic charges is formulated using two vector potentials, A and C. This has the aesthetic advantage of treating electric and magnetic charge both as gauge symmetries, but it has the experimental disadvantage of introducing a second massless gauge boson (the “magnetic” photon) which is not observed. This problem is dealt with by using the Higgs mechanism t...
متن کاملUniversal Seesaw Mass Matrix Model with an S 3 Symmetry
Stimulated by the phenomenological success of the universal seesaw mass matrix model, where the mass terms for quarks and leptons fi (i = 1, 2, 3) and hypothetical super-heavy fermions Fi are given by fLmLFR +FLmRfR + FLMFFR + h.c. and the form of MF is democratic on the bases on which mL and mR are diagonal, the following model is discussed: The mass terms MF are invariant under the permutatio...
