Sean, I agree with the notational change. I always found the “Seamus notation” confusing and less transparent. This is much more clear. Also, you can introduce a shorthand notation:

f_n = 1 – Sum_x f_x as the fraction of all events that are quasi-elastic (e,e’n). This notation should also make it easier to construct an unbinned maximum-likelihood estimator for “A_phys” as well, should we decide to pursue that option.

Cheers,
Andrew

Hi David,

This is great, thank you! I repeated the calculation, with the result highlighted at the end. The only difference I find is the polarization factors come in differently, but I assume this is just a factor from the different experiments.

Going forward I would like to use this formalism, so if any GEN experts have any objections to it please let me know before I get too deep in.

Best,
Sean

  Hope this makes sense; I can chat with you if something is unclear.
