The solutions depend on a mass integration constant, admit a smooth core of chosen regularity, and generically have an inner and outer event horizon. In particular, below a certain mass threshold, we find massive, horizonless, particle-like solutions. We scan through possible observational signatures ranging from weak to strong gravity and study the thermodynamics of our regular solutions, comparing them,","authors_text":"Christos Charmousis, Miguel San Juan, Mokhtar Hassaine, Olaf Baake","cross_cats":["gr-qc"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-th","submitted_at":"2021-04-16T16:56:39Z","title":"Regular black holes and gravitational particle-like solutions in generic DHOST theories"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2104.08221","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:6de90f4984bc72d6c28024239871fc02a181404763f51a30f3a663b9efbecc6e","target":"record","created_at":"2026-07-05T03:00:32Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"3bf198087ec7b718070cea6a3c2c8f2873dabd108f3fb887b87d214a2051257e","cross_cats_sorted":["gr-qc"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"hep-th","submitted_at":"2021-04-16T16:56:39Z","title_canon_sha256":"8f0ea258308f5315fd353aed9ff6b6af598f0df865771c278c70452af0a6e359"},"schema_version":"1.0","source":{"id":"2104.08221","kind":"arxiv","version":2}},"canonical_sha256":"5b3c34ca13e166d0eae11e6e458c74adfe9328a3a8a73582a6c5866889057b3d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5b3c34ca13e166d0eae11e6e458c74adfe9328a3a8a73582a6c5866889057b3d","first_computed_at":"2026-07-05T03:00:32.942555Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:00:32.942555Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"NqTLkRA2E8DffHrRKYWkQDNdm4SZfQBTQZeHRpM3PH3XN4bt9I4raBksaiGTmUcXk2a4vPb7BZKxDHDi2c6WBg==","signature_status":"signed_v1","signed_at":"2026-07-05T03:00:32.943098Z","signed_message":"canonical_sha256_bytes"},"source_id":"2104.08221","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6de90f4984bc72d6c28024239871fc02a181404763f51a30f3a663b9efbecc6e","sha256:986e9cdb53ffb1528271b9fbc5bf09f17f1f941dd291a48844f10eaef68a6352"],"state_sha256":"64df9100ef27df981a564a4f8e4f8b027c5138d001499dec84af70ee3147a568"}
