what PhD students would bother to use QCD ... given 28+-10 Mev accuracy
2 sf?
Grossman was ecstatic and astounded by 400,000 eV accuracy
for the n-p mass diff
QCD ,,, given time,,,maybe one thousand years
may achieve 1 eV accuracy
right now QCD is in the 500,000 to 10,000000 eV range,,
10 Mev accuracy for the binding energy of the He4..
Here is a 3eV accuracy for SO(4) for the He4 binding energy..
