Inflaton Oscillations and Post-Inflationary Reheating
Marcos A. G. Garcia, Kunio Kaneta, Yann Mambrini +1
We analyze in detail the perturbative decay of the inflaton oscillating about a generic form of its potential , taking into account the effects of non-instantaneous reh…
Disformal Dark Matter
Philippe Brax, Kunio Kaneta, Yann Mambrini +1
We generalize dark matter production to a two-metric framework whereby the physical metric, which couples to the Standard Model (SM), is conformally and/or disformally related to t…
Energy-Momentum portal to dark matter and emergent gravity
Pascal Anastasopoulos, Kunio Kaneta, Yann Mambrini +1
We propose a new scenario where dark matter belongs to a secluded sector coupled to the Standard Model through energy--momentum tensors. Our model is motivated by constructions whe…
Pair production of dark particles in meson decays
Matheus Hostert, Kunio Kaneta, Maxim Pospelov
Rare decays of and mesons provide a powerful probe of dark sectors with light new particles. We show that the pair production of dark states can be prob…
Reheating and Post-inflationary Production of Dark Matter
Marcos A. G. Garcia, Kunio Kaneta, Yann Mambrini +1
We perform a systematic analysis of dark matter production during post-inflationary reheating. Following the period of exponential expansion, the inflaton begins a period of damped…
