论文摘要
在平方$ t^2/z_2 $上绕的六个维度的质子衰减在树级时受到了高度抑制。这是因为仅包含零模式的BARYON数字（BNV）运算符必须满足选择规则$ \ frac {3} {2} {2}ΔB\ pm \ pm \ frac {1} {2} {2}Δl= 0 \ mod \ mod \ 4 $。在本文中，我们表明，上述关系不禁止质量尺寸6 BNV运算符，该操作员包含批量费米子的Kaluza Klein（KK）合作伙伴。这些新颖的操作员与Huperchage Gauge Boson（暗物质候选者）的“无旋转”伴随标量合作伙伴一起产生暗物质辅助质子衰变，该质子衰减在质量尺寸8处。在这里，有了违反相互作用的标量和矢量baryon数的明确示例，我们讨论了这种$ΔB= 1 = 1 =Δl$和$ΔB= 2 =Δl$运算符的重要性，并得出了新物理学的限制。
Proton decay in six dimensions orbifolded on square $T^2/Z_2$ is highly suppressed at tree-level. This is because baryon number violating (BNV) operators containing only the zero mode of bulk fermions must satisfy the selection rule $\frac{3}{2} ΔB \pm \frac{1}{2}ΔL = 0 \ mod \ 4$. In this article, we show that the above relation does not prohibit mass dimension-6 BNV operators containing Kaluza Klein (KK) partners of the bulk fermions. Together with `spinless' adjoint scalar partner of hypercharge gauge boson (the Dark Matter candidate), these novel operators generate Dark Matter assisted proton decay at mass dimension-8. Here, with explicit examples of scalar and vector baryon number violating interactions, we discuss the importance of such $ΔB=1 =ΔL$ and $ΔB=2=ΔL$ operators and derive the limit on New Physics.
