We study the transverse single spin asymmetry (SSA), AN, for the single inclusive process ℓp↑ → h + X, in a perturbative QCD factorization scheme with inclusion of spin and transverse momentum dependent (TMD) distributions. By adopting the relevant TMDs (Sivers and Collins functions) as extracted from semi-inclusive deep inelastic scattering (SIDIS) and e+e- data, predictions for these SSAs are given. A measurement of AN for this process could then provide a direct test of the validity of the TMD factorization.
