In each pair of lines for the same r0 (of the same colour) the best performance (lower WFE) occurs when L0 is smallest, unless the DM stroke is increased, which is expensive. The X axis of the graph runs backwards and corresponds to the maximum stroke available from a DM.

Although gluon fragmentation into colour-octet quark pairs appears as the most plausible explanation of the large direct ψ production cross section observed at the Tevatron, NRQCD factorization is still not definitely established on a quantitative level.
