Self-Interacting Dark Matter: From Particle Physics Theories to Structure Formation Simulations
Martin Rosenlyst, Vinh Tran, Oliver Zier +7
We establish a unified theory-to-simulation framework for self-interacting dark matter (SIDM) that integrates three components: (i) a comprehensive, self-contained treatment of its…
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…
Ruling out models of vector dark matter in asymptotically safe quantum gravity
Gustavo P. de Brito, Astrid Eichhorn, Mads T. Frandsen +3
The nature of dark matter is a problem with too many potential solutions. We investigate whether a consistent embedding into quantum gravity can decimate the number of solutions to…
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 Ch…
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…
Vector dark matter in supercooled Higgs portal models
Mads T. Frandsen, Matti Heikinheimo, Mattias E. Thing +2
We consider extensions of the Standard Model by a hidden sector consisting of a gauge field coupled with a scalar field. Assuming the absence of dimensionful parameters in the tree…
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…
Electroweak precision tests of composite Higgs models
Mads T. Frandsen, Martin Rosenlyst
We study constraints on Composite Higgs models with fermion partial compositeness from electroweak precision measurements, including the 2022 -boson mass result from the CDF col…
Composite self-interacting dark matter and Higgs
Martin Rosenlyst
We propose a novel mechanism in composite models that provides self-interacting dark matter along with the Higgs itself as composite particles, alleviating the Standard Model natur…
Technically natural Higgs boson from Planck scale
Martin Rosenlyst
We propose UV complete (Partially) Composite Higgs models with compositeness scale up to the Planck scale assisted by a novel mechanism. This mechanism is based on softly breaking…
Techni-Composite Higgs models with (a)symmetric dark matter candidates
Giacomo Cacciapaglia, Mads T. Frandsen, Wei-Chih Huang +2
We propose a novel class of composite models that feature both a technicolor and a composite Higgs vacuum limit, resulting in an asymmetric dark matter candidate. These Techni-Comp…
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…
Partially composite Higgs models: Phenomenology and RG analysis
Tommi Alanne, Diogo Buarque Franzosi, Mads T. Frandsen +3
We study the phenomenology of partially composite-Higgs models where electroweak symmetry breaking is dynamically induced, and the Higgs is a mixture of a composite and an elementa…
