The Strange Quark Polarisation from Charged Kaon Production on Deuterons
arXiv:0901.3690 · doi:10.1063/1.3215669
Abstract
The strange quark helicity distribution Delta s(x)is derived at LO from the semi-inclusive and inclusive spin asymmetries measured by the COMPASS experiment at CERN. The significance of the results is found to depend critically on the ratio of the sbar and u quark fragmentation functions into positive kaons.
