The obtained results indicate that with the vector anomalous couplings included Z boson and photon, the crosssections for the Z production are much larger than that with the scalar couplings included radion and Higgs under the same conditions.

We present one-loop formulas for contributing to the HZZ vertex in ’t Hooft-Veltman gauge within Standard Model framework. One-loop off-shell Higgs decay rates to Z-pair are investigated in both unpolarized and longitudinal polarization for Z bosons in final state. The corrections are range of 7% to 8.4% when we vary the off-shell Higgs mass from 200 GeV to 500 GeV.

The pair production of Higgs is studied with the contribution of the scalar unparticle in the e+ e- collision in the Randall-Sundrum model in detail. The total cross-section with the unparticle contribution is compared to that without the unparticle

The production of the Higgs boson and pho Abstract ton from the l+ l− collision when beams l+ l− are unpolarized and polarized are studied in detail in the Randall – Sundrum model (RS). Based on the results, we show that the advantageous direction to observe Higgs boson is the same direction of the lepton l− or antilepton l+.

The Higgs production was studied using the Randall-Sundrum model from photonphoton collision. The independent parameters in the Randall-Sundrum model: The vacuum expectation value of the radionfield A0, the radion mass M0, the Higgs mass Mh and E must be specified to fix the state mixing parameters.

Taking into account the 125 GeV Higgs boson and radion propagators, we investigate the e−e+ production via yy collision in the Randall-Sundrum model at International Linear Collider (ILC). The observable cross-sections are calculated for the diphoton collision. The cross-sections are evaluated with dependence on the collision energy √s, the polarization of electron and positron beams.

Despite the prediction of the Higgs boson at Large Hadron Collider (LHC) in the CERN in 2012 after it has been theorized for over 50 years, however, the Standard model (SM) still can not explain the mass of neutrinos; the hierarchy problem; the contribution of dark energy, dark matter and CP violation in cosmology.

This paper studies the production of Higgs boson and vector U unparticle, which has been proposed as an option for u+,u- collision by s, t, u-channels in the Randall-Sundrum model. The cross-section is presented and numerical evaluation is detailed.

Axion in PQWW model and axion production in e+e− collision Properties of the axion in PQWW model is considered. In this model, axion appears as a new phase of the Higgs field. From a general Higgs potential which is renormalizable and invariant under UPQ(1) transformation, we consider the interaction of the axion with leptons and quarks. Based on these results, axion production in e+e− collision is calculated in detail. The numerical evaluation shows that the axion can be detected in experimental conditions.

We study the Higgs-radion mixing and photon collisions. We consider the radion production in high energy photon collisions to search for the radion in the Randall-Sundrum model. Numerical evaluation gives observable cross-section in the future colliders.

We study the production of Higgs and Z bosons which has been proposed as an option of e+e − collision at the ILC, CLIC with the polarization of the electron and positron beams in Randall-Sundrum model (RSM). The differential cross-sections are presented and numerical evaluation is given. Based on the results, we show that the advantageous direction to collect Higgs is perpendicular to the direction of the initial e− beam. With the high integrated luminosity and at the high degree of polarization, the reaction can give observable cross-sections in future accelerators (ILC, CLIC).
