Measurement of azimuthal asymmetries in inclusive charged dipion production in e+e- annihilations at √s = 3.65 GeV

We present a measurement of the azimuthal asymmetries of two charged pions in the inclusive process e+e−→ππX, based on a data set of 62  pb−1 at the center-of-mass energy of 3.65 GeV collected with the BESIII detector. These asymmetries can be attributed to the Collins fragmentation function. We obs...
