N2 - A determination of the CP-even fraction F+ in the decay D0→K+K-π+π- is presented. Using 2.93 fb-1 of e+e-→ψ(3770)→DD¯ data collected by the BESIII detector, one charm meson is reconstructed in the signal mode and the other in a CP eigenstate or the decay D→KS,L0π+π-. Analysis of the relative rates of these double-tagged events yields the result F+=0.730±0.037±0.021, where the first uncertainty is statistical and the second is systematic. This is the first model-independent measurement of F+ in D0→K+K-π+π- decays.
