论文摘要
我们探索一类现实的超对称性翻转$ su（5）$ su（5）$型号的质子衰减，这些$ u（1）_r $ symmetry在实施混合通货膨胀中起着至关重要的作用。确定了基于逆Seesaw和I型SEESAW的两个不同的中微子质量模型，后者是由于$ u（1）_r $通过非肾上腺功能符号的超电势项而引起的。根据中微子质量模型，来自希格斯超级场地的适当中等尺度的色系在质子衰变通道中起关键作用，其中包括$ p \ rightarrow（e^{+}，μ^+），μ^+）\，π^0 $，$ p \ rightarrow（e^+，μ^{+，μ^{+，k^0 $， π^{+} $，$ p \ rightarrow \overlineν\，k^+ $。我们确定了在Hyper-Kamiokande和其他下一代实验中可测试的参数空间区域，这些区域可产生质子寿命估计。我们讨论如何在存在中等规模粒子的存在下量规耦合统一，并利用$ Z_4 $对称性来显示在Flop $ SU（5）$中如何出现此类中间尺度。最后，我们将质子衰变的预测与基于$ SU（5）$的先前工作和翻转$ SU（5）$进行比较。
We explore proton decay in a class of realistic supersymmetric flipped $SU(5)$ models supplemented by a $U(1)_R$ symmetry which plays an essential role in implementing hybrid inflation. Two distinct neutrino mass models, based on inverse seesaw and type I seesaw, are identified, with the latter arising from the breaking of $U(1)_R$ by nonrenormalizable superpotential terms. Depending on the neutrino mass model an appropriate set of intermediate scale color triplets from the Higgs superfields play a key role in proton decay channels that include $p \rightarrow (e^{+},μ^+)\, π^0$, $p \rightarrow ( e^+,μ^{+})\, K^0 $, $p \rightarrow \overlineν\, π^{+}$, and $p \rightarrow \overlineν\, K^+ $. We identify regions of the parameter space that yield proton lifetime estimates which are testable at Hyper-Kamiokande and other next generation experiments. We discuss how gauge coupling unification in the presence of intermediate scale particles is realized, and a $Z_4$ symmetry is utilized to show how such intermediate scales can arise in flipped $SU(5)$. Finally, we compare our predictions for proton decay with previous work based on $SU(5)$ and flipped $SU(5)$.
