Strong Supercooling as a Consequence of Renormalization Group Consistency
Vedran Brdar, Alexander J. Helmboldt, Manfred Lindner
Classically scale-invariant models are attractive not only because they may offer a solution to the long-standing gauge hierarchy problem, but also due to their role in facilitatin…
Type-I Seesaw as the Common Origin of Neutrino Mass, Baryon Asymmetry, and the Electroweak Scale
Vedran Brdar, Alexander J. Helmboldt, Sho Iwamoto +1
The type-I seesaw represents one of the most popular extensions of the Standard Model. Previous studies of this model have mostly focused on its ability to explain neutrino oscilla…
Observational prospects for gravitational waves from hidden or dark chiral phase transitions
Alexander J. Helmboldt, Jisuke Kubo, Susan van der Woude
We study the gravitational wave (GW) signature of first-order chiral phase transitions (PT) in strongly interacting hidden or dark sectors. We do so using several effective mode…
Conformal Realization of the Neutrino Option
Vedran Brdar, Yannick Emonds, Alexander J. Helmboldt +1
It was recently proposed that the electroweak hierarchy problem is absent if the generation of the Higgs potential stems exclusively from quantum effects of heavy right-handed neut…
Quark flavour-violating Higgs decays at the ILC
Daniele Barducci, Alexander J. Helmboldt
Flavour-violating Higgs interactions are suppressed in the Standard Model such that their observation would be a clear sign of new physics. We investigate the prospects for detecti…
Prospects for three-body Higgs boson decays into extra light scalars
Alexander J. Helmboldt, Manfred Lindner
Within models containing a very light scalar particle coupled to the 125 GeV Higgs boson, we present the first detailed study of Higgs decays into three of these light scalars. We…
Minimal conformal extensions of the Higgs sector
Alexander J. Helmboldt, Pascal Humbert, Manfred Lindner +1
In this work we find the minimal extension of the Standard Model's Higgs sector which can lead to a light Higgs boson via radiative symmetry breaking and is consistent with the phe…
Towards quantitative precision in the chiral crossover: masses and fluctuation scales
Alexander J. Helmboldt, Jan M. Pawlowski, Nils Strodthoff
We investigate the relation between the physical pion pole and screening masses and the mesonic fluctuation scale in low-energy QCD, which relates to the curvature of the mesonic e…
