Description
We present a neural-network global analysis of transversity parton distributions and dihadron fragmentation functions using Belle, HERMES, COMPASS, and STAR measurements. The main new ingredient is an x-dependent lattice-QCD determination of isovector transversity, included directly at positive and negative x. It complements the limited experimental coverage and favors a larger positive up-quark and a more negative down-quark transversity while retaining an acceptable description of the world data.
