Abstract

Inclusive hadron production cross sections and angular distributions in e+e− collisions shed light on fundamental questions of hadronization and fragmentation processes. We present measurements of the so-called Collins azimuthal asymmetries in inclusive production of hadron pairs in e+e− → h1h2X annihilation process, where the two hadrons (either kaons or pions) are produced in opposite hemispheres. In particular, this is the first measurement in e+e− annihilation experiment of the KK and Kπ azimuthal asymmetries, which allow to better understand the fragmentation processes and the role of the strage quark, and can be used as a tool to explore the spin content of the nucleon.
