Descrizione
The study of the transverse-momentum dependence of pairs of hadrons
produced in $e^+e^-$ annihilation in opposite hemispheres
provides access to transverse-momentum-dependent fragmentation functions. At present, the study of pairs of charge-separated pions, kaons and protons as a function of their relative transverse momentum and their fractional energy using the Belle $e^+e^-$ data is ongoing. The results of this ongoing analysis will be presented.
