abstract
We present the first extraction of the transversity distribution in the framework of collinear factorization based on the global analysis of pion-pair production in deep-inelastic scattering off transversely polarized targets and in proton-proton collisions with one transversely polarized proton. The extraction relies on the knowledge of di-hadron fragmentation functions, which are taken from the analysis of electron-positron annihilation data. For the first time, the chiral-odd transversity is extracted from a global analysis similar to what is usually done for the chiral-even spin-averaged and helicity distributions. The knowledge of transversity is important for, among other things, detecting possible signals of new physics in high-precision low-energy experiments.

The paper proposes that one-point energy correlators in transversely polarized proton-proton collisions access the nucleon's transversity distribution through a single-spin asymmetry with sin(φ_s - φ_n) angular dependence over a wider kinematic range than traditional transverse momentum measurements
A new approach using near-side energy-energy correlators in dihadron fragmentation enables extraction of nucleon transversity PDF in collinear factorization without modeling intrinsic transverse momentum or dihadron resonances.
Proposal for a new observable—dihadron azimuthal asymmetry in unpolarized SIDIS at EIC—that isolates linear dependence on light-quark dipole couplings via SM-dipole interference.
