Angular dependences in inclusive two-hadron production at BELLE

Boer, Daniel

Understand

A collection of results is presented relevant for the analysis of azimuthal asymmetries in inclusive two-hadron production at BELLE.

  • The aim of this overview is to provide theoretical ingredients necessary to extract the Collins effect fragmentation function.
  • The latter arises within the Collins-Soper factorization formalism, which describes both the transverse momentum and Q^2 dependence of the cross section and its angular dependences at low and moderate transverse momentum.
  • Since the Collins effect is not the only source of angular dependences, a discussion of various other effects is included.
