Description
Gauge coupling unification in the Supersymmetric Standard Models strongly implies the
Grand Unified Theories (GUTs). With the grand desert hypothesis, we show that
the supersymmetric GUTs can be probed at the future proton-proton (pp) colliders and
Hyper-Kamiokande experiment. For the GUTs with the GUT scale $M_{GUT} \le 1.0\times 10^{16}$~GeV,
we can probe the dimension-six proton decay via heavy gauge boson exchange
at the Hyper-Kamiokande experiment. Moreover, for the GUTs with
$M_{GUT} \ge 1.0\times 10^{16}$~GeV, we for the first time study the upper bounds
on the gaugino and sfermion masses. We show that the GUTs with anomaly and
gauge mediated supersymmetry breakings are well within the reaches of
the future 100 TeV pp colliders such as the ${\rm FCC}_{\rm hh}$ and SppC,
and the supersymmetric GUTs with gravity mediated supersymmetry breaking
can be probed at the future 160 TeV pp collider.
