We introduce and discuss two inter-related mechanisms operative in theelectroweak sector of the Standard Model at high energies. Higgsplosion, thefirst mechanism, occurs at some critical energy in the 25 to 10^3 TeV range,and leads to an exponentially growing decay rate of highly energetic particlesinto multiple Higgs bosons. We argue that this a well-controllednon-perturbative phenomenon in the Higgs-sector which involves the final stateHiggs multiplicities n in the regime n \lambda >> 1 where \lambda is the Higgsself-coupling. If this mechanism is realised in nature, the cross-sections forproducing ultra-high multiplicities of Higgs bosons are likely to becomeobservable and even dominant in this energy range. At the same time, however,the apparent exponential growth of these cross-sections at even higher energieswill be tamed and automatically cut-off by a related Higgspersion mechanism. Asa result, and in contrast to previous studies, multi-Higgs production does notviolate perturbative unitarity. Building on this approach, we then argue thatthe effects of Higgsplosion alter quantum corrections from very heavy states tothe Higgs boson mass. Above a certain energy, which is much smaller than theirmasses, these states would rapidly decay into multiple Higgs bosons. The heavystates become unrealised as they decay much faster than they are formed. Theloop integrals contributing to the Higgs mass will be cut off not by the massesof the heavy states, but by the characteristic loop momenta where their decaywidths become comparable to their masses. Hence, the cut-off scale would bemany orders of magnitude lower than the heavy mass scales themselves, thussuppressing their quantum corrections to the Higgs boson mass.
