论文摘要
我们在$ \ mathrm {so}（10）中得出阈值校正，$ grand Unified模型，中间对称性被翻转$ \ mathrm {su}（5）\ times \ times \ times \ mathrm {u}（1）$或$ \ MATHRM {SU}（3）\ TIMES \ MATHRM {SU}（2）（2）\ Times \ Mathrm {u}（1）\ Times \ Times \ MathRM {U}（1）$，带有Scalar域由生存假设设置的标量字段的质量。如果匹配条件不考虑阈值校正，这些模型将无法实现量规耦合统一。我们提出的结果显示了中间和统一量表的任何值所需的阈值校正大小。特别是，我们的结果表明，这两个模型都不受欢迎，因为它们需要较大的阈值校正以允许统一以高于当前实验界限的预测质子寿命。
We derive the threshold corrections in $\mathrm{SO}(10)$ grand unified models with the intermediate symmetry being flipped $\mathrm{SU}(5)\times\mathrm{U}(1)$ or $\mathrm{SU}(3)\times\mathrm{SU}(2)\times\mathrm{U}(1)\times\mathrm{U}(1)$, with the masses of the scalar fields set by the survival hypothesis. These models do not achieve gauge coupling unification if the matching conditions do not take threshold corrections into account. We present results showing the required size of threshold corrections for any value of the intermediate and unification scales. In particular, our results demonstrate that both of these models are disfavored since they require large threshold corrections to allow for unification with a predicted proton lifetime above current experimental bounds.
