Bag model predictions for polarized structure functions and theirQ 2-evolutions

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

It is shown that modified versions of the MIT bag model can fairly describe non-singlet pieces of experimentally known structure functions if theQ 2-evolution equations are trusted down to the model scale. Further on we utilize these models to study the presently unmeasured transversely polarized structure functionsg 2 andh 1. Using recently developed approximate evolution equations we focus on the relevance of the twist-3 contribution tog 2. Finally, a simple ‘first guess’-model for the ‘transversity’ distributionh 1 is presented.
