摘要: 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 chainsand present the sparticle spectrum.

摘要: We calculate the dependence on intermediate scale of the gaugino mass ratios upon breaking of SO(10) into the SM via an intermediate group H. We see that the ratios change significantly when the intermediatescale is low (say, 108 GeV or 1 Tev) compared to the case when the two breakings occur at thesame scale.
