Overview of fragmentation function measurements

Fragmentation functions describe how quasi-free, high energetic partons fragment into a number of confined final state hadrons. The precise knowledge of fragmentation functions is necessary for our understanding of hard scattering processes. Studying electron-positron annihilation provides the cleanest access to fragmentation functions. This talk will give an overview of the latest experimental results about fragmentation functions, such as the measurement of transverse polarization of lambda hyperons, invariant-mass and fractional-energy dependence of inclusive production of di-hardons and the production rate of hyperons and charmed baryons. An outlook towards the study of hadronization at the Belle II experiment which will take data at SuperKEKB will also be presented.
