我们提出了超对称标准模型的最小（最小）版本，它可以解决的层次问题，以同样的方式作为所谓的最小超对称标准模型（MSSM），并提出解决方案，它的一些问题。超对称性在一个隐蔽的扇区中被打破，并通过规范群G的信使介导到可观测扇区，前两代在该规范群G下变换。群G自发地（几乎）超对称破缺，破缺的尺度最多比规范信使M_* \sim 10^{15} GeV的尺度低几个数量级。通过规范介导，前两代费米子获得超对称破缺质量\hat m \sim 10 TeV.超对称破缺也是由引力介导的，它产生TeV量级的所有sfermion、Higgsinos和gauginos的质量，并通过D项有效算符提供合适的μ和B μ参数值。如果重力调解是最小味违反，则不存在超对称味问题。在R宇称存在的情况下，暗物质可以是最轻的中性伴子，就像在MSSM中一样，而LHC模型的现象学特征是只有第三代方子和slepton存在。
英文摘要：
We propose the minimal (Least) version of the Supersymmetric Standard Model which can solve the hierarchy problem in the same way as the so-called Minimal Supersymmetric Standard Model (MSSM) and presents solutions to some of its problems. Supersymmetry is broken in a secluded sector and mediated to the observable sector by messengers of a gauge group G under which the first two generations transform. The group G spontaneously breaks (almost) supersymmetrically at a scale at most a few orders of magnitude below the scale of gauge messengers M_*\sim 10^{15} GeV. By gauge mediation sfermions of the first two generations acquire supersymmetry breaking masses \hat m \sim 10 TeV. Supersymmetry breaking is also mediated by gravity which generates masses for all sfermions, Higgsinos and gauginos at the TeV scale and can provide appropriate values to the μand B_μparameters by D-term effective operators. If gravity mediation is Minimal Flavor Violating there is no supersymmetric flavor problem. In the presence of R-parity dark matter can be the lightest neutralino, as in the MSSM, and the LHC model phenomenology is characterized by the fact that only third generation squarks and sleptons are present.
In this lectures, we give a review about the Minimal Supersymmetric Standard Model (MSSM) with $R$-Parity Violation because it provides an attractive way to generate neutrino masses, lepton mixing angles in acconcordance to present neutrino data.
We review very nice mechanism to generate masses to all the neutrinos in the Minimal Supersymmetric Standard Model (MSSM) without break $R$-parity. In consequence we get viable axion as Dark Matter candidate and at the same time solve the $μ$-problem in a similar way as done in the Next to Minimal Supersymmetric Model (NMSSM).
We review the TeV scale $B-L$ extension of the Minimal Supersymmetric Standard Model (BLSSM) where an inverse seesaw mechanism of light neutrino mass generation is naturally implemented and concentrate on its hallmark manifestations at the Large Hadron Collider (LHC).
Some Recent Results from the Generic Supersymmetric Standard Model
一般的超对称标准模型是一个由超对称化的标准模型场谱建立的模型，只有规范对称性。流行的最小超对称标准模型与一般模型的不同之处在于，它具有人工强加的R-奇偶性。我们回顾了一个有效的制定模型和最近获得的一些有趣的现象学特征。后者包括对标量质量的R宇称破坏贡献，这在很大程度上被忽略了，以及对费米子电偶极矩和$μ\to e γ$的相关贡献。
Using Feynman-'t Hooft gauge and dimensional regularization, the static parity-violating coupling of the neutrinos and charged leptons to an external electromagnetic field is calculated in the minimal supersymmetry standard model (MSSM). From the obtained result of calculations, we have seen that the main contribution come from chargino particles in MSSM.
We study electroweak baryogenesis in the E_6 inspired exceptional supersymmetric standard model ( E_6SSM ). The relaxation coefficients driven by singlinos and the new gaugino as well as the transport equation of the Higgs supermultiplet number density in the E_6SSM are calculated. Our numerical simulation shows that both CP-violating source terms from singlinos and the new gaugino can solely give rise to a correct baryon asymmetry of the Universe via the electroweak baryogenesis mechanism.
We have explored the possibilities of scenarios with heavy gluinos and light stops in supersymmetric (SUSY) standard models with extra vector-like multiplets. If we assume the hierarchical structure for soft masses of the minimal supersymmetric standard model (MSSM) scalar fields and extra scalars, the light stop and the observed Higgs boson can be realized. While the stau is the lightest SUSY particle (LSP) in broad parameter space, we have found that the neutralino LSP is realized in the case that the non-zero soft parameters for the MSSM Higgs doublets or the non-universal gaugino masses ar…
