Abstract
In unpolarized electron‐positron annihilation, there may exist interesting and possibly non‐zero azimuthal asymmetries, which measure novel chiral‐odd fragmentation functions, such as the Collins‐Heppelmann function, H1⊥, and the two‐pion interference fragmentation function, δq̂h. We will present the experimental method to extract these functions using e+e− collision data from the Belle experiment at KEK B‐factory (KEKB). In addition to the considerable interest in the properties of these new fragmentation functions, they are expected to be a powerful tool in accessing proton quark transversity distributions.
