Journal Article
Khoze, V. V., & Spannowsky, M. (2018). Higgsplosion: Solving the hierarchy problem via rapid decays of heavy states into multiple Higgs bosons. Nuclear Physics B, 926, 95-111. https://doi.org/10.1016/j.nuclphysb.2017.11.002

We introduce and discuss two inter-related mechanisms operative in the electroweak sector of the Standard Model at high energies. Higgsplosion, the first mechanism, occurs at some critical energy in the 25 to 103 TeV range, and leads to an exponentia...

Higgsploding universe (2017)
Journal Article

Higgsplosion is a dynamical mechanism that introduces an exponential suppression of quantum fluctuations beyond the Higgsplosion energy scale E ∗ and further guarantees perturbative unitarity in multi-Higgs production processes. By calculating the Hi... Read More about Higgsploding universe.

Multiparticle production in the large λn limit: realising Higgsplosion in a scalar QFT (2017)
Journal Article

In a scalar theory which we use as a simplified model for the Higgs sector, we adopt the semiclassical formalism of Son for computations of n-particle production cross-sections in the high-multiplicity n → ∞ weak-coupling λ → 0 regime with the value...

Simplified models of dark matter with a long-lived co-annihilation partner (2017)
Journal Article
Khoze, V. V., Plascencia, A. D., & Sakurai, K. (2017). Simplified models of dark matter with a long-lived co-annihilation partner. Journal of High Energy Physics, 2017(6), 1-28. https://doi.org/10.1007/jhep06%282017%29041

We introduce a new set of simplified models to address the effects of 3-point interactions between the dark matter particle, its dark co-annihilation partner, and the Standard Model degree of freedom, which we take to be the tau lepton. The contribut... Read More about Simplified models of dark matter with a long-lived co-annihilation partner.

Towards the next generation of simplified Dark Matter models (2017)
Journal Article
Albert, A., Bauer, M., Brooke, J., Buchmueller, O., Cerdeño, D. G., Citron, M., …Wardle, N. (2017). Towards the next generation of simplified Dark Matter models. Physics of the Dark Universe, 16, 49-70. https://doi.org/10.1016/j.dark.2017.02.002

This White Paper is an input to the ongoing discussion about the extension and refinement of simplified Dark Matter (DM) models. It is not intended as a comprehensive review of the discussed subjects, but instead summarises ideas and concepts arising...
