在通过中间翻转SU（5）的$Z_{12-I}$轨道紧化中，利用Yukawa耦合结构得到了弦MSSM（${cal S}$MSSM）谱（三族、一对Higgs二重态和中性单线态）. GUT $sin^2 heta_W^0= frac 38 $，即使在扭曲扇区中有外来物，也可以通过GUT标度附近的矢量外来物的质量参数运行到观察到的电弱标度值。我们还得到了R宇称和二重态-三重态分裂。
In a $Z_{12-I}$ orbifold compactification through an intermediate flipped SU(5), the string MSSM (${cal S}$MSSM) spectra (three families, one pair of Higgs doublets, and neutral singlets) are obtained with the Yukawa coupling structure. The GUT $sin^2 heta_W^0=frac38$, even with exotics in the twisted sector, can be run to the observed electroweak scale value by mass parameters of vectorlike exotics near the GUT scale. We also obtain R-parity and doublet-triplet splitting.
