“…It is a remarkable observation that, whenever corrections to leading order DY cross sections were considered, absolute cross sections were found to be considerably altered (typically enhanced), but ratios of observables in DY were found to be only moderately altered. This is in particular the case for collinear double spin asymmetries, for example the double transverse spin asymmetry [111][112][113][114][115][116].…”

Intrinsic transverse parton momenta pT play an important role in the understanding of azimuthal/spin asymmetries in semi-inclusive deep-inelastic scattering (SIDIS) and the Drell-Yan process (DY). We review and update what is presently known about pT from these processes. In particular, we address the question to which extent data support the popular Gauss model for the pT -distributions. We find that the Gauss model works very well, and observe that the intrinsic transverse momenta in SIDIS and DY are compatible, which is a support for the factorization approach. As a byproduct we recover a simple but practical way of taking into account the energy dependence of pT -distributions.

“…16 Vogelsang and Weber [108] were the first to perform this calculation using massive gluons to regularise the divergences. Soon after the authors of [162] presented a calculation based on dimensional reduction. The result was then translated into dimensional regularisation in [61].…”

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.

“…They were also calculated (as part of the g 2 evolution) in [14][15][16][17]. The next-to-leading-order (NLO) DY coefficient functions were calculated in [18,19] while the NLO anomalous dimensions were calculated in [20][21][22]. The effects of evolution have been studied by many authors-for more details and a general review see, e.g., [1].…”
