Minimal Supersymmetric Standard Model

To solve the u problem of the Minimal Supersymmetric Standard Model (MSSM), a single field S is added to build the Next Minimal Supersymmetric Standard Model (NMSSM). Vacuum enlarged with non-zero vevs of the neutral-even CP is the combination of Hu, Hd and S.

In the NMSSM, there are seven Higgs bosons (while there are five ones in the MSSM) with three scalar CP-even Higgs S1,2,3 (ms1< ms2< ms3), two pseudoscalar CPodd Higgs P1,2 (mP1 < mP2) and a pair of charged Higgs h+.

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.

The formulae for the decay width and numerical results are obtained. We have calculated the conclusion of the one-loop vertex correction, wave-function correction and renormalization of the bare couplings to the decay width. We revealed that the effect of the complex parameters At and Ab could be quite significant in a large region of the MSSM parameter space.

In this paper, we study on the production of odd-CP higgs pair from annihilating collision of e+ e - pair, it's an opportunity to find new higgs in NMSSM.

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.

The minimal supersymmetric extension of the standard model (MSSM) superfields propagate in the bulk between the UV and IR branes at separated orbifold fixed points, while the hidden sector in charge of supersymmetry breaking is confined on the UV brane. We derive the 4D effective action from the original 5D action of the underlying theory. The effective 4D Yukawa couplings and all the soft supersymmetry breaking terms are calculated in terms of the 5D theory’s coefficients.

We present the appearance of some new interaction in the MSSM with CP violation. We give analytic formulae and perform an evaluation of the effects of these new interactions on some processes concerning the productions and decays of squarks. We find that these effects are typically of $-3.5 \% $ to $+3 \% $ depending on each process.
