Velocity-dependent self-interacting dark matter and composite Higgs
Martin Rosenlyst
We show that the mass of a self-interacting dark matter candidate, specifically a Dirac fermion, can be generated by composite dynamics, with a light scalar mediator emerging along…
Loop-Generated Neutrino Masses in Composite Higgs Models
Giacomo Cacciapaglia, Martin Rosenlyst
We present a composite scotogenic model for neutrino masses, which are generated via loops of -odd composite scalars. We consider three different approaches to the co…
XENON1T solar axion and the Higgs boson emerging from the dark
Giacomo Cacciapaglia, Chengfeng Cai, Mads T. Frandsen +2
In a recent letter we proposed a new non-thermal mechanism of Dark Matter production based on vacuum misalignment, where both the Higgs boson and a very light pseudo-scalar eme…
Natural Top-Bottom Mass Hierarchy in Composite Higgs Models
Martin Rosenlyst, Christopher T. Hill
We consider composite two-Higgs doublet models based on gauge-Yukawa theories with strongly interacting fermions generating the top-bottom mass hierarchy. The model features a sing…
Higgs boson emerging from the dark
Chengfeng Cai, Hong-Hao Zhang, Giacomo Cacciapaglia +2
We propose a new non-thermal mechanism of dark matter production based on vacuum misalignment. A global -charge asymmetry is generated at high temperatures, under which both the…
Dark matter in (partially) composite Higgs models
Tommi Alanne, Diogo Buarque Franzosi, Mads T. Frandsen +1
We construct composite and partially composite Higgs models with complex pseudo-Nambu--Goldstone (pNGB) dark matter states from four-dimensional gauge-Yukawa theories with strongly…
