Dear Savvas,

Evolution of the pion DA is proudly called "ERBL" 😉

Cheers,

"R"

Dear All,

Here are the points discussed...

Daniel K. showed his IT results for the pion DA for the N5 Nf=2 CLS ensemble a=0.048fm, m_ps~440MeV 48^3*96.

Chris M and Joe K asked to see if the trend of data before AP evolution goes towards the right direction.

Daniel K also showed for fixed p as a function of z^2….
Observed oscillation? Reasons behind? Look at Ji et al papers?
Kostas suggested fitting a polynomium in nu for each z as an interpolator…
Joe suggested not just pick nu = 2pi/L * 12 and study its special (p,z) combos…
do a loop over 2pi/L * n and find all (p,z) combos which multiply to n

GHP meeting…Deadline for support today…

SVD results on GPD data
Joe performed his own independent Jupyter code for gluons initially…

Issues:
flat directions
combinations of rows
zero singular values for non-zero kinematic factors?
Automation? JoeK: if it is all zeroes then throw it away…
Then A3, A5 =0 etc etc

Best,
Savvas
