Measurement of the tensor (A yy ) and vector (A y ) analyzing powers in the fragmentation of a 9-GeV/c deuteron on hydrogen and carbon nuclei at high proton transverse momenta

Abstract

Data on the tensor and vector analyzing powers (A yy and A y , respectively) in the fragmentation of a 9-GeV/c deuteron on hydrogen and carbon nuclei at high proton transverse momenta are presented. These data are compared with the results of relevant calculations performed within light-front dynamics by using various deuteron wave functions. The best description of the data is attained with the relativistic deuteron wave function derived within field-theory light-front dynamics.
