abstract
We perform the first global quantum chromodynamics (QCD) analysis of dihadron production for a comprehensive set of data in electron-positron annihilation, semi-inclusive deep-inelastic scattering, and proton-proton collisions, from which we extract simultaneously the transversity distributions of the nucleon and $\pi^+\pi^-$ dihadron fragmentation functions. We incorporate in our fits known theoretical constraints on transversity, namely, its small-$x$ asymptotic behavior and the Soffer bound. We furthermore show that lattice-QCD results for the tensor charges can be successfully included in the analysis. This resolves the previously reported incompatibility between the tensor charges extracted from dihadron production data and lattice QCD. We also find agreement with results for the transversity and tensor charges obtained from measurements on single-hadron production. Overall, our work demonstrates for the first time the universal nature of all available information for the transversity distributions and the tensor charges of the nucleon.

Transverse Charge Distribution as a Probe of Nucleon Transversity
A charge-flow measurement built only from track angles and charge signs contains a leading-twist chiral-odd dipole that matches the charge-weighted Collins moment, giving enhanced transversity-sensitive asymmetries.

Unveiling Light-Quark Yukawa Flavor Structure via Dihadron Fragmentation at Lepton Colliders
A dihadron fragmentation azimuthal asymmetry at e+e− colliders can probe light-quark Yukawa couplings linearly and separate y_u from y_d at the 10^-4 level.

Bell Inequality Violation of Light Quarks in Back-to-Back Dihadron Pair Production at Lepton Colliders
Using dihadron fragmentation functions as spin analyzers, the paper shows that Bell inequality violation in massless quark pairs can be probed through azimuthal correlations, with projected discovery significance from...

QCD factorization with multihadron fragmentation functions
The standard operator definition of fragmentation functions is shown to follow from collinear factorization for small-mass n-hadron final states, contrary to a recently proposed modified definition.

Anisotropic jet broadening and jet shape
The paper introduces azimuthal-dependent jet broadening and jet shape observables, calculates their jet functions in SCET for standard and Winner-Take-All axes, and shows the broadening can directly probe the collinea...
