Abstract 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.

- Semi-inclusive deep inelastic scattering at small transverse momentum (2006, background): “We consider the process ℓ(l) +N(P ) → ℓ(l′) + h(Ph) +X, (2.1) where ℓ denotes the beam lepton, N the nucleon target, and h the produced hadron, and where four-momenta are given in parentheses.”
- Effects of transversity in deep-inelastic scattering by polarized protons (2010, neutral): “fq 1(x) and g q 1(x) are related to the vector and axial charge of the nucleon, respectively. There is a third leading-twist PDF, the function hq 1(x)8, called the transversity distribution (see Ref. [5] for a review on the subject). Its integral over x is related to the tensor charge of the nucleon”
