2. Measurement of P T -weighted Sivers asymmetries in leptoproduction of hadrons / Alexeev, M.G. ; Alexeev, G.D. ; Amoroso, A. ; Andrieux, V. ; et al
The transverse spin asymmetries measured in semi-inclusive leptoproduction of hadrons, when weighted with the hadron transverse momentum PT , allow for the extraction of important transverse-momentum-dependent distribution functions. [...]
