Flavor separation of quark to Lambda-Baryon fragmentation

The neutrino and antineutrino deep inelastic scattering of unpolarized and polarized Lambda and productions can provide a clean separation of unpolarized and polarized fragmentation functions of a quark into a Lambda, for both light-flavor quarks and antiquarks and also for strange quarks. One can systematically measure or check the various flavor and spin dependent fragmentation functions by combining with Lambda and productions in polarized electron deep inelastic scattering. Such measurements can provide crucial tests of different predictions concerning the spin structure of hadrons and the quark-antiquark asymmetry of the nucleon sea.
