G. Miller's New b1 Calculations

Reading through G. Miller's paper that includes new calculations of b1 based on 6-quark, hidden color contributions, I thought I'd add his Fig. 4 plots to our proposal plot to see if we could potentially differentiate between the curves. It should be noted that this is only the 6-quark part, and doesn't include the 1-pion exchange. Because of this, these plots shouldn't be trusted below x~0.2.

Compared to Proposal

If I just add these to the plots we had on our proposal, it looks like:

W > 1.5 GeV

It looked like if we could squeeze another point out around 0.65, then there might be a chance to further constrain the model. However, this would require dropping our W cut from 1.85 to 1.50. The result would be:

Results

Finally, there's a lot going on in all of these plots. It we make the proposal W cut for the first 4 points, but lower it to add the 5th point, our ability to differentiate between the curves looks like:
