摘要: We discuss in detail the option to access transversity distribution function ${h}_{1}(x)$ by utilizing analyzing power of interference fragmentation functions two-pion production inside same current jet. The transverse polarization fragmenting quark is related component relative momentum hadron pair via a new azimuthal angle. As specific example, we spell out thoroughly way extract from measured single spin asymmetry inclusive lepton-nucleon scattering. To estimate sizes observable effects employ spectator model for functions. resulting our example discussed as arising different scenarios transversity.
