Transverse momentum dependence of fragmentation functions from Belle data

Abstract

In this paper, we present new sets of transverse momentum dependence of fragmentation functions (TMD FFs) along with their uncertainties. We include the most recent TMD production cross sections of π ± , K ± and p/p measured in single inclusive e + e − annihilation by Belle Collaboration. In this analysis, the common Gaussian distribution is applied for transverse momentum dependence (P HT) of the cross section. Our theory calculations over a wide range of transverse momentum P HT are in good agreement with Belle experimental data analyzed in this study.
