论文摘要
我们考虑一个非苏格对称$ e_6 $ grand统一理论(ut),具有中间的三位化对称$ su(3)_c \ times su(3)_l \ times su(3)_r \ times _r \ times _r \ times d $ d $(d表示为离散的左对称性的D- Parity),对左右的:费米和向量)。据观察,中间质量尺度$ m_i $和$ \ sin^2θ_w$仍然不受肠道阈值贡献的影响。阈值修改的统一质量尺度$ M_U $与当前的实验质子衰变约束非常一致。该模型的新功能是,仅发现$ M_U $的肠道阈值不确定性仅受超重量标量的控制,从而导致质子衰减的非常预测的情况,可以在可预见的实验中验证。
We consider a non-supersymmetric $E_6$ Grand Unified Theory (GUT) with intermediate trinification symmetry $SU(3)_C \times SU(3)_L \times SU(3)_R \times D$ (D denoted as D-parity for discrete left-right symmetry) and study the effect of one-loop threshold corrections arising due to every class of superheavy particles (scalars, fermions and vectors). It is observed that, the intermediate mass scale $M_I$ and $\sin^2θ_W$ remain unaffected by GUT threshold contributions. The threshold modified unification mass scale $M_U$ is in excellent agreement with the present experimental proton decay constraint. The novel feature of the model is that GUT threshold uncertainty of $M_U$ is found to be controlled by superheavy scalars only, leading to a very predictive scenario for proton decay, which can be verifiable within the foreseeable experiments.
