Chang, J.X. Wang and X.G. Wu, Comput.Phys.Commun.{\\bf 174}, 241(2006)]. This trick is helpful for experimental simulation. Moreover, the BCVEGPY output has also been improved, i.e. one Les Houches Event common block has been added so as to generate a standard Les Houches Event file that contains the information of the generated $B_c$ meson and the accompanying partons, which can be more conveniently used for further simulation.","authors_text":"Xian-You Wang, Xing-Gang Wu","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2011-08-11T16:13:13Z","title":"A Trick to Improve the Efficiency of Generating Unweighted $B_c$ Events from BCVEGPY"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1108.2442","kind":"arxiv","version":1},"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":"sha256:144009a9a835115754d8bb4b04d8b6d0481c981eeaf9c2aa2a25d0aa536f304b","target":"record","created_at":"2026-05-18T04:08:12Z","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":"f487df08ce4fedc3b7344fad568acfd7ec2fbb87c150d47abb47f3917541e486","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2011-08-11T16:13:13Z","title_canon_sha256":"fc9191836a22eb849308747f064949c8c76c47098fa0d79c02bf9bdcfcd88a24"},"schema_version":"1.0","source":{"id":"1108.2442","kind":"arxiv","version":1}},"canonical_sha256":"12d34744c739f043c904ceb145c5fcc80ed0cdcda4183e5ec4e7e205b37e8eab","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"12d34744c739f043c904ceb145c5fcc80ed0cdcda4183e5ec4e7e205b37e8eab","first_computed_at":"2026-05-18T04:08:12.298431Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:08:12.298431Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"m20VMuWB4HXENef0BRtpPI+2a5nTxy2IhMubeP03JQRkaMbNdwK8UHoC8+jCHBpm7Xi1QoitsUUMtevRKxniDA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:08:12.298846Z","signed_message":"canonical_sha256_bytes"},"source_id":"1108.2442","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:144009a9a835115754d8bb4b04d8b6d0481c981eeaf9c2aa2a25d0aa536f304b","sha256:6e195318bd5ef9d57097b43ea9553de093ff480501376fca81d579b8c897377a"],"state_sha256":"90160c18895184bfbd9c8027c43254c6686d2081436d9bb29596c2cbd02db3b7"}
