Extracting the transversity distributions from single-hadron and dihadron production

TL;DR

This paper determines valence transversity distributions using single-hadron and dihadron production data from semi-inclusive deep inelastic scattering and e+e- annihilation, without parametrization, finding consistent results across methods.

Contribution

It provides a point-by-point extraction of transversity distributions from two different processes without relying on parametrization, demonstrating their compatibility.

Findings

Transversity distributions are compatible across methods.

Extraction does not require parametrization.

Results are consistent with previous measurements.

Abstract

We present a point-by-point determination of the valence transversity distributions from two different types of processes: single-hadron production and dihadron production, both in semi-inclusive deep inelastic scattering and e+e- annihilation. The extraction is based on some simple assumptions and does not require any parametrization. The transversity distributions obtained from Collins effect in single-hadron production and from interference effects in dihadron production are found to be compatible with each other.
