To address the known shortfalls of such a fixed order calculation we introduce phenomenological parton distributions for initial transverse momentum and quark mass, and devise a subtraction scheme to avoid double-counting when utilizing the standard longitudinal parton distribution functions. We show that we can reproduce Drell-Yan transverse momentum and invariant mass spectra from different proton-proton, proton-nucleus and antiproton-nucleus experiments","authors_text":"Fabian Eichstaedt, Hendrik van Hees, Kai Gallmeister, Stefan Leupold, Ulrich Mosel","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2011-08-26T12:53:22Z","title":"Description of fully differential Drell-Yan pair production"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1108.5287","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":"sha256:662972e20e6c7aee2978fe0631354dd2679a480f15d27f393aa4c4ed26ac1771","target":"record","created_at":"2026-05-18T04:14:38Z","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":"82caffe29a14ef795e863050c07eab8444b7ada42498df22a0fafd64b1017b2b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2011-08-26T12:53:22Z","title_canon_sha256":"7a562c670d12a76841ae258371454a47e79d36b180994e60aa1bae6f7bbf0d80"},"schema_version":"1.0","source":{"id":"1108.5287","kind":"arxiv","version":1}},"canonical_sha256":"057578d4f7ee06666b448e847f6c91d3fc4cf664d2f6e736db7bb5c86ba0060b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"057578d4f7ee06666b448e847f6c91d3fc4cf664d2f6e736db7bb5c86ba0060b","first_computed_at":"2026-05-18T04:14:38.586018Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:14:38.586018Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"heyzmY8PXSHMRWexG42L79tBr/w+Gj51988Kr7SxomCGePYWQ9QYU4k7KEHP4pWenRE+MJq0IePbMdzU2aBuCA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:14:38.586550Z","signed_message":"canonical_sha256_bytes"},"source_id":"1108.5287","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:662972e20e6c7aee2978fe0631354dd2679a480f15d27f393aa4c4ed26ac1771","sha256:234b3c348dd45d4949f21a43cbfb02a6a095c5e2e7b87076ad30ecddb0e39fe8"],"state_sha256":"329192940307759508eb526795bed37a8bd2fbdc31c5d95f0af1ad4e5fcf0b3e"}
