We calculate the self-energy of the standard-model Higgs boson by means of the pinch technique. We work in the general R? gauge and show that the final result is independent of the gauge parameters. This result is useful in order to demonstrate that the t... see more

In this paper, we present O(a3)\mathcal{O}(\alpha^3) QED corrections due to initial-state photon radiation (ISR) to processes e-e+?f¯fHe^{-} e^{+} \to f \bar{f} H with f=e,µe,?µ,?tf = e, \mu_e, \nu_{\mu}, \nu_{\tau} at future lepton colliders. The impact ... see more

Randal-Sundrum models have an interesting feature that an effective physical scale can be generated from a much larger one of the underlying theory. In this paper, we investigate a model of supersymmetry in the Randall-Sundrum spacetime with a low cutoff ... see more

Conditions for spontaneous Charge-Parity (CP) violation in the scalar potential sector of general S(3) Higgs-doublet model (3HDM) are analyzed. An analysis of the Higgs sector of the minimal S(3)-invariant extension of the Standard Model including CP viol... see more

The standard model has postulated the existence of a scalar boson, named the Higgs boson (or the Brout-Englert-Higgs boson, for more complete). This boson plays a central role in a symmetry breaking scheme called the Higgs mechanism making the standard mo... see more

We consider the Randall - Sundrum model, which solves the Higgs hierarchy problem. In this paper, we have calculated the cross - section of the ?e-?he-\gamma e^{-} \rightarrow h e^{-} process with the polarization of the electron beams. Based on the resul... see more

We propose a new mechanism for creating the mass of gauge bosons independently of Higgs mechanism. The main idea is to introduce some scalar function of space-time coordinates in the gauge transformation with some appropriate constraints. The model also a... see more

In the Standard Model of particle physics massive fermions (quarks and leptons) and bosons (W^+-, Z^o, H^o) are needed. However, the logic of nature requires that the universe emerged out of the vacuum and therefore all elementary particles should be mass... see more
