“…Let us for the moment simply pose the question of the effect of QCD evolution [72,74,94,[98][99][100][101][102][103][104][105][106][107][108][109][110][111][112] on the overall magnitude of the transversity densities that might be constructed at some low-energy scale. As already noted above, there is no conservation rule associated with the tensor charge of the nucleon (cf.…”

We review the present state of knowledge regarding the transverse polarisation (or transversity) distributions of quarks. After some generalities on transverse polarisation, we formally define the transversity distributions within the framework of a classification of all leading-twist distribution functions. We describe the QCD evolution of transversity at leading and next-to-leading order. A comprehensive treatment of non-perturbative calculations of transversity distributions (within the framework of quark models, lattice QCD and QCD sum rules) is presented. The phenomenology of transversity (in particular, in Drell-Yan processes and semi-inclusive leptoproduction) is discussed in some detail. Finally, the prospects for future measurements are outlined.

“…Here a T T is the partonic transverse-spin asymmetry, calculable in perturbative QCD, and M is the dilepton mass. NLO corrections to Drell-Yan dimuon production with transversely polarized beams have been calculated [124,125,121,129,130] and are routinely used in numerical studies.…”
