Figure 7From: Exclusive ρ0 production in deep inelastic scattering at HERAThe 15 density-matrix elements obtained from a fit to the data (dots), as a function of Q2. Also shown in the figure are results from an earlier measurement [50] (open circles). The inner error bars indicate the statistical uncertainty, the outer error bars represent the statistical and systematic uncertainty added in quadrature. The dotted line at zero is the expectation from SCHC when relevant.Back to article page
