| مستخلص: |
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, H[sub 1][sup ⊥], and the two-pion interference fragmentation function, δq⁁h. 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. © 2003 American Institute of Physics [ABSTRACT FROM AUTHOR] |
