Displaced Vertices from Pseudo-Dirac Dark Matter
Alessandro Davoli, Andrea De Simone, Thomas Jacques +1
Displaced vertices are relatively unusual signatures for dark matter searches at the LHC. We revisit the model of pseudo-Dirac dark matter (pDDM), which can accommodate the correct…
Evaporation and scattering of momentum- and velocity-dependent dark matter in the Sun
Giorgio Busoni, Andrea De Simone, Pat Scott +1
Dark matter with momentum- or velocity-dependent interactions with nuclei has shown significant promise for explaining the so-called Solar Abundance Problem, a longstanding discrep…
Geometric Baryogenesis from Shift Symmetry
Andrea De Simone, Takeshi Kobayashi, Stefano Liberati
We present a new scenario for generating the baryon asymmetry of the universe that is induced by a Nambu-Goldstone (NG) boson. The shift symmetry naturally controls the operators i…
Spontaneous Baryogenesis without Baryon Isocurvature
Andrea De Simone, Takeshi Kobayashi
We propose a new class of spontaneous baryogenesis models that does not produce baryon isocurvature perturbations. The baryon chemical potential in these models is independent of t…
Towards the next generation of simplified Dark Matter models
Andreas Albert, Martin Bauer, Oliver Buchmueller +23
This White Paper is an input to the ongoing discussion about the extension and refinement of simplified Dark Matter (DM) models. Based on two concrete examples, we show how existin…
Cosmological Aspects of Spontaneous Baryogenesis
Andrea De Simone, Takeshi Kobayashi
We investigate cosmological aspects of spontaneous baryogenesis driven by a scalar field, and present general constraints that are independent of the particle physics model. The re…
