The decay contribution to the parity-odd fragmentation functions
Parity violation in QCD is a consequence of the so-called QCD θ-vacuum. As a result, parity-odd fragmentation functions are introduced and they bring in new observables in the back-to-back dihadron productions in e+e−-annihilation experiments [1]. The experimental measurements on the corresponding p...
