Description
Fragmentation functions describe the formation of confined hadrons from asymptotically-free, high-energetic partons. As they cannot be obtained from first principle calculations in QCD, they need to be extracted experimentally. Especially electron-positron annihilation is a process where they can be cleanly extracted due to the absence of hadrons in the initial state. However, also in other processes fragmentation functions can be accessed, such as semi-inclusive DIS or hadron-hadron collisions.
The recent measurements at B factories and plans from the sPHENIX experiment will be discussed.
