A new connection between WIMP dark matter and the hierarchy problem
Maximilian Detering, Thomas Steingasser, Tevong You
This work proposes a direct link between the hierarchy problem and Weakly Interacting Massive Particles (WIMPs): we suggest that the small mass of the Higgs boson arises from being…
Quantum tunneling from excited states in the steadyon picture
Joshua Lin, Bruno Scheihing-Hitschfeld, Thomas Steingasser
Recent developments in the understanding of real-time path integrals led to the development of the ``steadyon picture'' for the semi-classical calculation of quantum tunneling rate…
Path integral predictions for pre-asymptotic false vacuum decay
Joshua Lin, Bruno Scheihing-Hitschfeld, Thomas Steingasser
When tunneling occurs out of generic initial states, a significant fraction of probability is lost at early times during which the dynamics is governed by excited resonance states.…
Precision Unitarity Calculations in Inflationary Models
Thomas Steingasser, Mark P. Hertzberg, David I. Kaiser
We revisit perturbative unitarity in scalar field inflation with a nonminimal coupling, with Higgs inflation serving as the most prominent example. Although such models are phenome…
Higgs Criticality and the Metastability Bound: a target for future colliders
Maximilian Detering, Victor Enguita, Belen Gavela +2
New physics at the TeV scale or lower may destabilise the electroweak vacuum. How low could the vacuum instability scale be? This fundamental question may be tied to a deeper under…
Higgs near-criticality at future colliders
Victor Enguita, Belen Gavela, Thomas Steingasser
The so-called metastability bound on the Higgs mass suggests that the smallness of the Higgs mass may be a byproduct of the metastability of the electroweak vacuum. A significantly…
Gauge hierarchy and metastability from Higgs-driven crunching
Sean Benevedes, Ameen Ismail, Thomas Steingasser
We present a new solution to the Higgs hierarchy problem based on dynamical vacuum selection in a landscape scanning the Higgs mass. In patches where the Higgs mass parameter takes…
