Anselmino", "R. Kishore", "A. Mukherjee" ], "comment": "6 pages, 2 figures", "categories": [ "hep-ph" ], "abstract": "The transversity distribution for $u$ and $d$ quarks is usually extracted from data on spin asymmetries in Semi Inclusive Deep Inelastic Scattering (SIDIS): however, due to its chiral odd nature, it has to be coupled to another chiral odd function, typically the Collins or the di-hadron fragmentation function. A recent suggestion of considering SIDIS data involving ratios of spin asymmetries and avoiding a knowledge of the Collins function, is briefly discussed. New measurements, involving ratios of cross sections, are suggested. They would allow a direct extraction of the transversity ratio, $h_1^{d_V}/h_1^{u_V}$. Numerical estimates are given.", "revisions": [ { "version": "v1", "updated": "2020-09-07T15:07:29.000Z" } ], "analyses": { "keywords": [ "valence transversity distributions", "sidis data", "extraction", "inclusive deep inelastic scattering", "spin asymmetries" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable" } } }
