Strong Dark Matter Self-Interaction from a Stable Scalar Mediator
Mateusz Duch, Bohdan Grzadkowski, Da Huang
In face of the small-scale structure problems of the collisionless cold dark matter (DM) paradigm, a popular remedy is to introduce a strong DM self-interaction which can be genera…
Gauge-Independent Approach to Resonant Dark Matter Annihilation
Mateusz Duch, Bohdan Grzadkowski, Apostolos Pilaftsis
In spontaneously broken gauge theories, transition amplitudes describing dark-matter (DM) annihilation processes through a resonance may become highly inaccurate close to a product…
One-loop contribution to dark matter-nucleon scattering in the pseudoscalar dark matter model
Duarte Azevedo, Mateusz Duch, Bohdan Grzadkowski +3
Recent dark matter (DM) direct searches place very stringent constraints on the possible DM candidates proposed in extensions of the Standard Model. There are however models where…
Testing scalar versus vector dark matter
Duarte Azevedo, Mateusz Duch, Bohdan Grzadkowski +3
We investigate and compare two simple models of dark matter (DM): a vector and a scalar DM model. Both models require the presence of two physical Higgs bosons and whic…
Resonance enhancement of dark matter interactions: the case for early kinetic decoupling and velocity dependent resonance width
Mateusz Duch, Bohdan Grzadkowski
Motivated by the possibility of enhancing dark matter (DM) self-interaction cross-section , we have revisited the issue of DM annihilation through a Breit-Wigner reso…
