This problem is ameliorated in models with lower reheating temperature $T_R$, which allows for dilution of gravitationally produced relics. We study the freeze-in dark matter production mechanism in the thermal bath with the electroweak scale temperature. The process is Boltzmann-suppressed if the dark matter mass is above $T_R$. In this case, the coupling to the thermal bath has to be significant to account for the observed dark matter relic density. As a result, the direct DM detection experiments already probe such freeze-in models, excluding significant parts of parameter space. The forthcoming experiments will explore this framework further, extending to lower couplings and higher reheating temperatures.","external_url":"https://arxiv.org/abs/2306.13061","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-10T03:46:44.779371+00:00","pith_arxiv_id":"2306.13061","created_at":"2026-05-10T08:53:05.160478+00:00","updated_at":"2026-07-10T03:46:44.779371+00:00","title_quality_ok":false,"display_title":"Cosme, F","render_title":"Cosme, F"},"hub":{"state":{"work_id":"d428835e-c34e-4773-a6e9-2c4dc3cbe45b","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":17,"external_cited_by_count":null,"distinct_field_count":1,"first_pith_cited_at":"2025-11-07T02:25:39+00:00","last_pith_cited_at":"2026-07-09T16:32:17+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-08-21T00:49:56.382818+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":6}],"polarity_counts":[{"context_polarity":"background","n":6}],"runs":{},"summary":{},"graph":{},"authors":[]}}
