Holography and Brane-bulk Energy Exchange

, 2005
The five-dimensional description of generalized Randall-Sundrum cosmology is mapped via holography to a generalization of the Starobinsky model. This provides a holographic dual description of the cosmological brane-bulk energy exchange processes studied

LHC / ILC / Cosmology Interplay [PDF]

, 2006
There is a strong and growing interplay between particle physics and cosmology. In this talk, I discuss some aspects of this interplay concerning dark matter candidates put forth by theories beyond the Standard Model.

Hunting the dark Higgs

Journal of High Energy Physics, 2017
We discuss a novel signature of dark matter production at the LHC resulting from the emission of an additional Higgs boson in the dark sector. The presence of such a dark Higgs boson is motivated simultaneously by the need to generate the masses of the ...

Dark matter from a complex scalar singlet: the role of dark CP and other discrete symmetries

Journal of High Energy Physics, 2021
We study the case of a pseudo-scalar dark matter candidate which emerges from a complex scalar singlet, charged under a global U(1) symmetry, which is broken both explicitly and spontaneously.

New Light Species and the CMB

, 2013
We consider the effects of new light species on the Cosmic Microwave Background. In the massless limit, these effects can be parameterized in terms of a single number, the relativistic degrees of freedom.

Electroweak symmetric dark matter balls

Journal of High Energy Physics, 2019
In the simple Higgs-portal dark matter model with a conserved dark matter number, we show that there exists a non-topological soliton state of dark matter.

Non-minimal (self-)running inflation: metric vs. Palatini formulation

Journal of High Energy Physics, 2021
We consider a model of quartic inflation where the inflaton is coupled non-minimally to gravity and the self-induced radiative corrections to its effective potential are dominant.

Dark Matter from Minimal Flavor Violation

, 2011
We consider theories of flavored dark matter, in which the dark matter particle is part of a multiplet transforming nontrivially under the flavor group of the Standard Model in a manner consistent with the principle of Minimal Flavor Violation (MFV). MFV

Inflation and dark matter in the inert doublet model

Journal of High Energy Physics, 2017
We discuss inflation and dark matter in the inert doublet model coupled non-minimally to gravity where the inert doublet is the inflaton and the neutral scalar part of the doublet is the dark matter candidate.

Freeze-in, glaciation, and UV sensitivity from light mediators

Journal of High Energy Physics, 2022
Dark matter (DM) freeze-in through a light mediator is an appealing model with excellent detection prospects at current and future experiments. Light mediator freeze-in is UV-insensitive insofar as most DM is produced at late times, and thus the DM ...
