摘要:

我们考虑明确的统一模型的基础上翻转的${SU(5)\times U(1)}$和$SU(6)\times SU(2)$规范群,规范介导的质子衰变算子被抑制在领先的顺序,由于统一多重态的物质场的特殊位置。我们讨论了这些模型的理论结构和现象学意义。对于后者,我们研究的可行性的物理谱在每种情况下,并专注于可能存在的其他运营商,也可能大大有助于质子衰变率。

英文摘要:

We consider explicit unified models based on the flipped ${SU(5)\times U(1)}$ and $SU(6)\times SU(2)$ gauge groups in which gauge mediated proton decay operators are suppressed at leading order due to the special placement of matter fields in unified multiplets. We discuss both the theoretical structure and phenomenological implications of these models. For the latter, we examine the viability of the physical spectrum in each scenario and focus on the possible presence of other operators that could also contribute significantly to the proton decay rate.
