论文摘要
Susy $ SO（10）$肠子处于严重的张力，并且在质子部分寿命上的实验界限，因为彩色希格西诺斯（dimension-five-five proton衰减）介导的质子衰减太快了。在本文中，我们追求的可能性是，在可恢复的susy $ so（10）$ ut模型中，Yukawa耦合矩阵的质地抑制了尺寸五质质子衰减。我们专注于一般可统计的SUSY $ SO（10）$ gut模型，其中包含$ {\ bf 10}+{\ bf 126}+{\ bf \ edline {126}}+{\ bf 120} $表示字段，以及Yukawa coupling of the $ coupling the $ bf bf bf bf bf bf bf bf bf bf bf bf bf。 $ {\ bf 10} $，$ {\ bf \覆盖{126}} $，$ {\ bf 120} $ fields，$ y_ {10}，y_ {126}，y_ {120} $，提供Quark和Lepton Yukawa couplans and Marteled Nevlet Nevlet singlet of Singlet of Singlet of Singlet of Singlet。我们发现，如果以某些风味库为基础的组件，$（y_ {10}）_ {u_r d_r} $，$（y_ {126}）_ {u_r d_r} $，$（y__ {10}） $（y_ {10}）_ {u_l d_l} $，$（y_ {126}）_ {u_l d_l} $，$（y_ {10}）_ {u_l s_l s_l s_l s_l} $，$（y____ {126}） u_l} $，$（y_ {126}）_ {u_l u_l} $，全部按照UP Quark Yukawa耦合的顺序，可以抑制dimension-five proton衰减，而Yukawa耦合矩阵仍然可以再现现实主义的Quark和Lepton Mose和Lepton Mose和Lepton Mose和Flashe Cixes。我们从数值上获得满足上述条件的特定Yukawa耦合矩阵，从中计算质子部分寿命，并评估当满足这些条件时尺寸五质量质子衰减如何抑制。
The SUSY $SO(10)$ GUT is in severe tension with the experimental bounds on proton partial lifetimes because proton decay mediated by colored Higgsinos (dimension-five proton decay) is too rapid. In this paper, we pursue the possibility that a texture of the Yukawa coupling matrices in a renormalizable SUSY $SO(10)$ GUT model suppresses dimension-five proton decay. We focus on a general renormalizable SUSY $SO(10)$ GUT model which contains ${\bf 10}+{\bf 126}+{\bf \overline{126}}+{\bf 120}$ representation fields and where the Yukawa coupling matrices of the ${\bf 16}$ matter fields with the ${\bf 10}$, ${\bf \overline{126}}$, ${\bf 120}$ fields, $Y_{10},Y_{126},Y_{120}$, provide the quark and lepton Yukawa couplings and Majorana mass of the singlet neutrinos. We find that if components in certain flavor bases, $(Y_{10})_{u_R d_R}$, $(Y_{126})_{u_R d_R}$, $(Y_{10})_{u_R s_R}$, $(Y_{126})_{u_R s_R}$, $(Y_{10})_{u_L d_L}$, $(Y_{126})_{u_L d_L}$, $(Y_{10})_{u_L s_L}$, $(Y_{126})_{u_L s_L}$, $(Y_{10})_{u_L u_L}$, $(Y_{126})_{u_L u_L}$, are all on the order of the up quark Yukawa coupling, dimension-five proton decay can be suppressed while the Yukawa coupling matrices still reproduce the realistic quark and lepton masses and flavor mixings. We numerically obtain specific Yukawa coupling matrices satisfying the above conditions, calculate proton partial lifetimes from them and evaluate how dimension-five proton decay is suppressed when these conditions are met.
