Observational Properties of Feebly Coupled Dark Matter
Matti Heikinheimo, Tommi Tenkanen, Kimmo Tuominen +1
We show that decoupled hidden sectors can have observational consequences. As a representative model example, we study dark matter production in the Higgs portal model with one rea…
Vector resonances at LHC Run II in composite 2HDM
Stefano Di Chiara, Matti Heikinheimo, Kimmo Tuominen
We consider a model where the electroweak symmetry breaking is driven by strong dynamics, resulting in an electroweak doublet scalar condensate, and transmitted to the standard mod…
Observational Constraints on Decoupled Hidden Sectors
Matti Heikinheimo, Tommi Tenkanen, Kimmo Tuominen +1
We consider an extension of the Standard Model with a singlet sector consisting of a real (pseudo)scalar and a Dirac fermion coupled with the Standard Model only via the scalar por…
Dark-Photon searches via Higgs-boson production at the LHC
Sanjoy Biswas, Emidio Gabrielli, Matti Heikinheimo +1
Dark photons mediating long-range forces in a dark sector are predicted by various new physics scenarios, and are being intensively searched for in experiments. We extend…
Simulations of Galaxy Cluster Collisions with a Dark Plasma Component
Christian Spethmann, Hardi Veermäe, Tiit Sepp +4
Dark plasma is an intriguing form of self-interacting dark matter with an effective fluid-like behavior, which is well motivated by various theoretical particle physics models. We…
