Transversity K Factors for Drell-Yan | | Philip G. Ratcliffe
; | | Date: |
13 Dec 2004 | | Journal: | Eur.Phys.J. C41 (2005) 319-325 | | Subject: | hep-ph | | Abstract: | The question of the K factor in transversely polarised Drell-Yan (DY) processes is examined. The transverse-spin case is peculiar for the absence of a reference point in deeply inelastic scattering (DIS). Therefore, in order to study more fully the possible effects of higher-order corrections on DY asymmetries, a DIS definition for transversity is devised using a hypothetical scalar (Higgs-like) vertex. The results show that some care may be required in interpreting experimentally extracted partonic transversity, in particular when comparing with model calculations or predictions. | | Source: | arXiv, hep-ph/0412157 | | Services: | Forum | Review | PDF | Favorites | |
