Abelian symmetry

This paper is organized as follows. In Section 2, we briefly describe the model including the particle content and the symmetry. In Section 3, we focus on the scalar particles and derive their interaction terms. In Section 4, we investigate the decay channel of a new scalar to a pair of the 125 GeV Higgs bosons. Finally, the conclusion is presented in Section 5.

This article considers the SU(2) gauge field coupled with the two Higgs fields. We obtain the non-Abelian solutions of the corresponding field equations. For the constant solution, the gauge field and the two Higgs fields correspond to unbroken local SU(2) symmetry at large distance.

This paper investigate an extension of the standard model with vector-like fermions and an extra Abelian gauge symmetry. The particle mass spectrum is calculated explicitly. The Lagrangian terms for all the gauge interactions of leptons and quarks in the model are derived. Observe that while there is no new mixing in the lepton sector, the quark mixing plays an important role in the magnitudes of gauge interactions for quarks, particularly the interactions with massive W, Z and Z0 bosons.

In this paper, the formulation of theories extended by an additional Abelian gauge symmetry in the superfield formalism is presented. By rotating in the space of the gauge fields, the gauge kinetic mixing term can be eliminated, and the relevant charge and coupling are shifted in comparison with the original quantities. We demonstrate, for example, the effect of the gauge kinetic mixing term in the case of the U(1) extension of the minimal supersymmetric standard model.

Many classical integrable systems (like the Euler, Lagrange and Kowalewski tops or the Neumann system) as well as finite dimensional reductions of many integrable PDEs share the property of being algebraically completely integrable systems4. This means that they are completely integrable Hamiltonian systems in the usual sense and, moreover, their complexified invariant tori are open subsets of complex Abelian tori on which the complexified flow is linear. To such systems the powerful algebro-geometrical techniques may be applied...
