Journal Article
Ghoshal, A., Heurtier, L., & Paul, A. (2022). Signatures of non-thermal dark matter with kination and early matter domination. Gravitational waves versus laboratory searches. Journal of High Energy Physics, 2022(12), Article 105. https://doi.org/10.1007/jhep12%282022%29105

The non-thermal production of dark matter (DM) usually requires very tiny couplings of the dark sector with the visible sector and therefore is notoriously challenging to hunt in laboratory experiments. Here we propose a novel pathway to test such a... Read More about Signatures of non-thermal dark matter with kination and early matter domination. Gravitational waves versus laboratory searches.
