论文摘要
我们基于量规对称$ su(4)_C \ times su(2)_l \ times su(2)_r $的质子对称混合膨胀模型中讨论质子衰变。 a $ u(1)\,r $对称性在实现通货膨胀以及消除一些违反运营商的一些不良的bary数字方面起着至关重要的作用。质子衰减主要是由手性超级场外的各种颜色三胞胎介导的,它在可观察的范围内,对于三胞胎的一系列中等规模质量。衰减模式包括$ p \ rightarrow e^{+}(μ^+)+π^0 $,$ p \ rightarrow \ rightArrow \barν+π^{+} $,$ p \ rightarrow k^0+ e^+(μ^{+} {+} {+}) $ 10^{34} -10^{36} $ yrs,可在Hyper-Kamiokande和Future升级处访问。简要讨论了最小的超对称标准模型(MSSM)量规耦合的大统一理论(GUT)尺度$ M _ {\ rm gut} $($ \ sim 10^{16} $ GEV)。
We discuss proton decay in a recently proposed model of supersymmetric hybrid inflation based on the gauge symmetry $SU(4)_c \times SU(2)_L \times SU(2)_R$. A $U(1)\, R$ symmetry plays an essential role in realizing inflation as well as in eliminating some undesirable baryon number violating operators. Proton decay is primarily mediated by a variety of color triplets from chiral superfields, and it lies in the observable range for a range of intermediate scale masses for the triplets. The decay modes include $p \rightarrow e^{+}(μ^+) + π^0$, $p \rightarrow \barν + π^{+}$, $p \rightarrow K^0 + e^+(μ^{+})$, and $p \rightarrow K^+ + \barν$, with a lifetime estimate of order $10^{34}-10^{36}$ yrs and accessible at Hyper-Kamiokande and future upgrades. The unification at the Grand Unified Theory (GUT) scale $M_{\rm GUT}$ ($\sim 10^{16}$ GeV) of the Minimal Supersymmetric Standard Model (MSSM) gauge couplings is briefly discussed.
