Here $'X'$ denotes any inclusive hadronic state and $Q$ represents the invariant mass of the lepton pair. All QCD partonic subprocesses have been included provided the lepton pair is created by a virtual photon, which is a valid approximation for $Q<50$ GeV. Unlike the differential distribution w.r.t. transverse momentum the dominant subprocess for the integrated cross section is given by $q+\\bar q \\to γ^* + 'X'$ and its higher order corrections so that massive lepton pair production provides us with an excellent tool to measure the polarized anti-quark densities. Our calculations are carried out using the method of $n$-dimensional regularization by making a special choice for the $γ_5$ matrix. We give predictions for double longitudinal spin asymmetry measurements at the RHIC.","is_dataset_classified":null,"base_score":0.0,"endowment":0.0,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":null,"pmcid":null,"openalex_id":null,"authors":[],"funders":[{"funder_name":"National Science Foundation","grant_id":"0098527","title":"Theoretical Physics"}],"total_grants":1,"fwci":null,"citation_percentile":null,"influential_citations":0,"citation_trend":[],"oa_status":"green","license":"Elsevier TDM","oa_locations":[{"url":"https://arxiv.org/pdf/hep-ph/0311304","host_type":"repository"},{"url":"https://api.elsevier.com/content/article/PII:S0550321304000161?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0550321304000161?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.nuclphysb.2004.01.001","host_type":""},{"url":"http://arxiv.org/pdf/hep-ph/0311304","host_type":""},{"url":"https://dx.doi.org/10.48550/arxiv.hep-ph/0311304","host_type":""},{"url":"http://arxiv.org/abs/hep-ph/0311304","host_type":""},{"url":"https://dx.doi.org/10.1016/j.nuclphysb.2004.01.001","host_type":""}],"fields_of_study":["0103 physical sciences","01 natural sciences"],"mesh_terms":[],"keywords":["High Energy Physics - Phenomenology","High Energy Physics - Phenomenology (hep-ph)","FOS: Physical sciences"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-29T17:32:25.927075Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
