我们考虑SUSY SO（10）模型，其中SUSY破缺通过不转化为SO（10）单态的F项发生。这导致了非普适的GUT尺度的高吉诺质量，导致了与最小超引力模型（mSUGRA）中预期的不同的超粒子质量模式。我们研究了SO（10）的三个断裂链，它们分别通过SU（4）×SU（2）×SU（2），SU（2）×SO（7）和“翻转”SU（5）从SO（10）的伴随的对称乘积中得到.我们研究了对应于不同断裂链的不同边界条件的唯象意义，并给出了s粒子谱。
We consider SUSY SO(10) models in which SUSY-breaking occurs via an F-term which does not transform as an SO(10) singlet. This results in non-universal GUT-scale gaugino masses leading to a different pattern of sparticle masses from what is expected in the minimal supergravity model (mSUGRA). We study three breaking chains of SO(10) down to the standard model through SU(4)×SU(2)×SU(2), SU(2)×SO(7) and ‘flipped’ SU(5) achieved by the representations 54 and 210 which appear in the symmetric product of two SO(10) adjoints. We examine the phenomenological implications of the different boundary conditions corresponding to the different breaking chains and present the sparticle spectrum.
