Dark matter production and reheating via direct inflaton couplings: collective effects
Dark matter production and reheating via direct inflaton couplings: collective effects
We study scalar dark matter production and reheating via renormalizable inflaton couplings, which include both quartic and trilinear interactions. These processes often depend crucially on collective effects such as resonances, backreaction and rescattering of the produced particles. To take them into account, we perform lattice simulations and map out parameter …
