A Novel Implementation of Self-Interacting Dark Matter in AREPO
Oliver Zier, Xuejian Shen, Vinh Tran +3
Self-interacting dark matter (SIDM) influences halo structure through collisional heat transport and may solve several small-scale puzzles in structure formation. SIDM creates ther…
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…
Gravitational waves from composite Higgs models
Mads T. Frandsen, Matti Heikinheimo, Martin Rosenlyst +2
We study possible strong first-order electroweak phase transitions in Composite Higgs models and we quantify the part of parameter space that can be probed with future gravitationa…
Bridging the Hz gap in the gravitational-wave landscape: unveiling dark baryons
Martin Rosenlyst
We study gravitational waves (GWs) with frequencies in the Hz range, which arise from phase transitions related to dark confinement in the context of dark versions of Quantum C…
Addressing Six Standard Model Problems with Technically Natural Higgs Models
Martin Rosenlyst
We aim to study the potential of the recently proposed model framework, called Technically Natural Higgs (TNH), in addressing six fundamental problems in particle physics and cosmo…
