[d2n-analysis-talk] DNP 2013 Talk [Version 1]

[Zein-Eddine Meziani]

Hi Dave,

Two comments:

1- Our data do not add to the precision of delta u /u, only new world proton data could do that.
Have you used updated data in semi-inclusive (and perhaps inclusive) data from Hermes for deltau/u?

2- In you abstract you mention "a_2^n", the second moment of the g1n structure function and lattice but not in your talk. It would be good to to say something about it to be in par with your abstract. You have everything it takes to evaluate it, and we do have Göckle et al. lattice calculations of this quantity to compare.
