The aim of this work is to investigate the occurrence two different spontaneous symmetry breakings at levels description fermion-scalar field model, by means a set gap equations and with background effective action. For that, we consider Yukawa as toy model for interactions between nonmassive fermions intermediated self-interacting real scalar field. This has stake symmetries classical level kn...

In standard quantum mechanics, it is not possible to directly extend the Schrödinger equation to spinors, so the Pauli equation must be derived from the Dirac equation by taking its non-relativistic limit. Hence, it predicts the existence of an intrinsic magnetic moment for the electron and gives its correct value. In the scale relativity framework, the Schrödinger, Klein-Gordon and Dirac equat...

We apply the BMHV scheme for non-anticommuting $\gamma_5$ to an abelian chiral gauge theory at two-loop level. As our main result, we determine full structure of symmetry-restoring counterterms up These turn out have same as one-loop level and a simple interpretation in terms restoration well-known Ward identities. In addition, show that ultraviolet divergences cannot be canceled completely by ...

in this paper the telemac-3d model has been hired to simulate and study the high waves’ interaction with coastal structures. therefore a special arrangement of telemac-3d has been prepared in this study to simulate wave generation, coastal processes, wave set-up and overtopping over coastal structures. experimental data has been used to verify this arrangement of the model. thereafter, the mode...

We discuss the necessity of a right-handed Weyl neutrino due to the vector-like phenomenon of the regularized Standard Model. It is shown that this right-handed neutrino is decoupled from low energies as a free particle, and Dirac neutrino masses are very small. We suggest gauge-invariant couplings between down quarks and charged leptons so that charged leptons acquire masses without extra Golt...

The role of spin and orbital rotational symmetry on the laser-induced magnetization dynamics itinerant-electron ferromagnets was theoretically investigated. ultrafast demagnetization transition metals is shown to be direct consequence fundamental breaking these conservation laws in electronic system, an effect that inherent nature spin-orbit electron-lattice interactions. A comprehensive analys...

On the basis of previous work on chiral gauged fermions on a lattice, we discuss the lattice-regularization of the standard model by introducing two Weyl fields interacting with quarks and leptons. These interactions form massive bound states to gauge-invariantly decouple doublers at high energies and these bound states dissolve into their constituents at low energies. No any hard spontaneous s...

We determine the vacuum structure of N=2 supersymmetric QCD with fundamental quarks for gauge groups SO(n) and Sp(2n), extending prior results for SU(n). The solutions are all given in terms of families of hyperelliptic Riemann surfaces of genus equal to the rank of the gauge group. In the scale invariant cases, the solutions all have exact Sdualities which act on the couplings by subgroups of ...
