作为我们先前工作的延续，基于大沙漠假设，我们证明可以在未来的质子-质子对撞机和超神冈实验中探测具有规范传递的超对称大统一理论（GUTs）。对于GUT能标 $M_{\rm GUT}$ 小于或等于 $0.84\times10^{16}$ GeV，通过重规范玻色子交换的维数为六的质子衰变寿命小于或约为 $5\times10^{34}$ 年，因此我们可以在超神冈实验中探测它。对于 $M_{\rm GUT} \ge 0.84 \times 10^{16}$ GeV，最轻的中性子是次轻超对称粒子（NLSP），并且胶微子以及前两代夸克的质量上限分别为8.64 TeV和11.82 TeV。因此，胶微子和前两代夸克可以在未来的100 TeV质子-质子对撞机如 ${\rm FCC}_{\rm hh}$ 和SppC中被探测。此外，我们讨论了有色超粒子、轻子、赝标量希格斯粒子和电弱微子的质量谱。如果超粒子被发现，它可能为我们提供关于介子能标、有效超对称破缺能标以及超对称破缺软项的重整化群演化的线索。
英文摘要
As a continuation of our previous work, with the grand desert hypothesis, we prove that we can probe the Supersymmetric Grand Unified Theories (GUTs) with gauge meidation at the future proton-proton collider and Hyper-Kamiokande experiment. For the GUT scale $M_{\rm GUT}$ less than or equal to $0.84\times10^{16}$~GeV, the proton lifetime for dimension-six proton decay via heavy gauge boson exchange is less than or around $5\times10^{34}$ years, and thus we can probe it at the Hyper-Kamiokande experiment. For $ M_{\rm GUT} \ge 0.84 \times 10^{16}$ GeV, the lightest neutralino is the Next to the Lightest Supersymmetric Particle (NLSP), as well as the upper mass bounds on the gluino and first two generation squarks are 8.64 TeV and 11.82 TeV, respectively. Therefore, the gluino and first two generation squarks can be probed at the future 100 TeV proton-proton collider such as ${\rm FCC}_{\rm hh}$ and SppC. Moreover, we discuss the mass spectra for the colored sparticles, sleptons, pseudo-scalar Higgs and electroweakinos. If the sparticles were discovered, it might give us hint on the messenger scale, the effective supersymmetry breaking scale, and the renormalization group evolution of the supersymmetry breaking soft terms.
