In transversely polarized p\u2191 + p collisions it can be accessed using transverse polarization dependent fragmentation functions which give rise to azimuthal correlations between the polarization of the struck parton and the final state scalar mesons.\nThis letter reports on spin dependent di-hadron correlations measured by the STAR experiment. The new dataset corresponds to 25 pb\u22121 integrated luminosity of p\u2191 + p collisions at \u221as = 500 GeV, an increase of more than a factor of ten compared to our previous measurement at \u221as = 200 GeV. Non-zero asymmetries sensitive to transversity are observed at a Q 2 of several hundred GeV and are found to be consistent with the former measurement and a model calculation. We expect that these data will enable an extraction of transversity with comparable precision to current SIDIS datasets but at much higher momentum transfers where subleading effects are suppressed.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_27": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Elsevier"}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1016/j.physletb.2018.02.069", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "\u00a9 2018 The Author(s).
