摘要：
我们发现，新的最小超对称（SO（10））大统一理论（NMGUT）的物质汤川耦合受到非常显着的大统一理论尺度阈值修正。包括这些阈值效应放松约束$ y_b-y_τ\simeq y_s-y_μ$操作在$\textbf{10} -\textbf{120} $小生成树级MSSM物质费米子yukawas $y_f$。我们发现精确的拟合的MSSM费米子质量混合数据的NSSGUT超势耦合和5个独立的软Susy打破参数$M_0, M_{1/2}, A_0, M^2_{H,\bar{H}}$在$M_X$。拟合一般具有升高的统一尺度$M_X$接近$M_{Planck}$，$α_3(M_Z)$的可行值，并且与B违反、$b\rightarrow sγ$、μ子磁矩异常和标准模型$ρ$参数的当前限制一致。相关的新的和独特的软Susy光谱有轻gauginos，一个\emph{normal} s-层次和比诺LSP。Bino LSP伴随着第二代和第一代右手征sfermions光足以调解一致的WIMP暗物质共湮灭宇宙学，并在LHC中可被验证，而第三代sfermions在LHC的3-50 TeV的不可验证范围内。发现的拟合需要$|μ|,|A_0|\sim 100$ TeV，这意味着深CCB/UFB minimae和宇宙学时间尺度上的MSSM标准真空的稳定性。我们的研究结果表明，一个一致的现实的现象可能是指定的SO（10）（NMS）GUT参数在$M_X$单独和一个新的可行部门的软超对称性参数空间可能存在，如果味违反约束可以满足在43维参数空间。
英文摘要：
We show that matter yukawa couplings of the New Minimal Supersymmetric (SO(10)) GUT(NMSGUT) are subject to very significant GUT scale threshold corrections. Including these threshold effects relaxes the constraint $ y_b-y_τ\simeq y_s-y_μ$ operative in $\textbf{10} -\textbf{120} $plet generated tree level MSSM matter fermion yukawas $y_f$. We find accurate fits of the MSSM fermion mass-mixing data in terms of NMSGUT superpotential couplings and 5 independent soft Susy breaking parameters $M_0, M_{1/2}, A_0, M^2_{H,\bar{H}}$ at $M_X$. The fits generally have elevated unification scale $M_X$ near $M_{Planck}$, viable values of $α_3(M_Z)$, and are consistent with current limits on B violation, $b\rightarrow sγ$, muon magnetic moment anomaly and Standard Model $ρ$ parameter. The associated novel and distinctive soft Susy spectra have light gauginos, a \emph{normal} s-hierarchy and Bino LSP. The Bino LSP is accompanied by second and first generation right chiral sfermions light enough to mediate a consistent WIMP dark matter co-annihilation cosmology and to be discoverable at LHC, while third generation sfermions are in the LHC undiscoverable range of 3-50 TeV. The fits found require $|μ|,|A_0|\sim 100$ TeV which imply both deep CCB/UFB minimae and stability of the MSSM standard vacuum on cosmological time scales. Our results indicate that a consistent realistic phenomenology may be specifiable in terms of SO(10) (NMS)GUT parameters at $M_X$ alone and that a new viable sector of the soft supersymmetry parameter space may exist if flavour violation constraints can be satisfied in the 43 dimensional parameter space.
