We apply the variational method to the relativistic Hamiltonian with the Gaussian-type trial wave function to obtain the values of $\\beta$ (scale parameter). Then with the help of known values of constituent quark masses, we obtain the numerical results for the decay constants $f_P$ and $f_V$, respectively. We compare our numerical results with the existing experimental data.","authors_text":"Harleen Dahiya, Nisha Dhiman","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-02-13T07:55:24Z","title":"Ratios of vector and pseudoscalar $B$ meson decay constants in the light-cone quark model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.04493","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":"sha256:52c2160eb8b287e980bf1b72d473707ca07c4e5f6020eac2a79e7ef11333d96f","target":"record","created_at":"2026-05-18T00:19:21Z","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":"6e25296c683e423a8995db4c3db505a10d655fd2a3a4815ece041e9cd1b195aa","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2018-02-13T07:55:24Z","title_canon_sha256":"a16d0526e6e47b323615a0f7ce9c3fe6e24591ac622e60b2a05a6cc0a3c38b67"},"schema_version":"1.0","source":{"id":"1802.04493","kind":"arxiv","version":2}},"canonical_sha256":"65064f3ebc67ab5d1fc0cc985267882b6d98d774707f9aefa398a9a23d38385c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"65064f3ebc67ab5d1fc0cc985267882b6d98d774707f9aefa398a9a23d38385c","first_computed_at":"2026-05-18T00:19:21.031311Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:19:21.031311Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"FXfxdnt2XCR8dNnieRqwPJcf7Xmb4hfa+zKDY2sLPDNcU2iL847+hoZa5na5K4F8BJyFIhUcHXMZVUALseR/AQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:19:21.031854Z","signed_message":"canonical_sha256_bytes"},"source_id":"1802.04493","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:52c2160eb8b287e980bf1b72d473707ca07c4e5f6020eac2a79e7ef11333d96f","sha256:629333acae90a4f11f468d88e003586dcc4e268a1af842e4e6f41dc59a23b9c1"],"state_sha256":"233fe255f60f61cd098b038af4d6d089acf03a4895131a8a34bd4a501529a5fd"}
