论文摘要
在手性$ su（15）$量规理论中，标准模型费米子是无质量预位的状态，我们表明质子 - 纽约操作员可能是在综合量表中诱导的，$λ_ {\ rm pre} $。我们通过搜索质子衰变对极限的估计为$λ_ {\ rm pre}> 10^4 \，{\ rm tev}^{1/2} \，c_8^{1/4} {1/4} \ \ \ \，m _ {\ cal q}^}^{1/2} $，$ c_8 $ a co foter an 8-prector $ coperon an 8-cofter an 8-cofter an 8-pre cofter an 8-cofter an 8-pre an 8-cofter由$ su（15）$ dynamics诱导，$ m _ {\ cal q} $是复合矢量夸克的质量。后者具有与复合载体式Lepton的质量相关的下限，而LHC搜索又需要高于1 TEV。对于$ 10^{ - 5} - 1 $范围，对于$ C_8 $，$λ_{\ rm pre} $的下限在$ 3 \ times 10^3 $ tev和$ 5 \ times 10^4 $ tev之间变化。我们指出，可以使用Super-Kamiokande或Dune探测器观察到异国质子衰减模式，即$π^+$和沉重的右中微子。
Within a chiral $SU(15)$ gauge theory in which the Standard Model fermions are bound states of massless preons, we show that proton-decay operators are likely induced at the compositeness scale, $Λ_{\rm pre}$. Our estimate of the limit imposed by searches for proton decays is $Λ_{\rm pre} > 10^4 \, {\rm TeV}^{1/2} \, C_8^{1/4} \, m_{\cal Q}^{1/2}$, where $C_8$ is a rescaled coefficient of an 8-prebaryon operator induced by $SU(15)$ dynamics, and $m_{\cal Q}$ is the mass of a composite vectorlike quark. The latter has a lower limit related to the mass of a composite vectorlike lepton, which in turn is required by LHC searches to be above 1 TeV. For $C_8$ in the $10^{-5} - 1$ range, the lower limit on $Λ_{\rm pre}$ varies between $3 \times 10^3$ TeV and $5 \times 10^4$ TeV. We point out that exotic proton decay modes, into a $π^+$ and a heavy right-handed neutrino, could be observed using the Super-Kamiokande or DUNE detectors.
