We consider two data sets, one referring to the associated production of $\\Lambda$'s with a light unpolarized hadron in an almost back-to-back configuration, and one for the inclusive $\\Lambda$ production, with the reconstruction of the thrust axis. We adopt the Collins-Soper-Sterman framework and employ the recent formulation on the factorization of single-inclusive hadron production.
