Kaon fragmentation functions from COMPASS 2006 kaon multiplicities* — •Daniel Hahne — Physikalisches Institut Bonn
Knowledge of unpolarized fragmentation functions (FFs) is essential for the flavor separation of spin dependent parton distribution functions (PDFs). Fragmentation functions are extracted based on hadron multiplicities in semi-inclusive deep inelastic scattering where at least one final state hadron is identified. I will present the latest results of kaon FFs extracted from COMPASS 2006 K± multiplicities on an isoscalar target.
Due to different experimental acceptances for the reconstruction of charged and neutral kaons, KS0 multiplicities have an extended kinematic range compared to K± multiplicities.
I will discuss the possible impact of additional KS0 multiplicities on the extraction of kaon FFs.
