This updates the tabulated heavy coefficient functions using adani-v1.1.1. In addition to the addition of the exact expression of the matching condition $a^{(3)}_{Qg}$ in v1.0.6 (which is currently the tip of master) this new version introduces an improved parametrization of the small-x part.

The results are consistent with NNPDF40@N3LO but with much smaller uncertainties except for the singlet at large $\eta$ where we see some differences:

C2S_3_Q2m2_2.0.pdf
C2g_3_Q2m2_4.0.pdf
C2g_3_Q2m2_2.0.pdf

For the record, here are the same comparisons using v1.0.8:

C2S_3_Q2m2_4.0.pdf
C2S_3_Q2m2_2.0.pdf
C2g_3_Q2m2_4.0.pdf
C2g_3_Q2m2_2.0.pdf

NOTE: As confirmed by Niccolò, in our case, we should always use a damping factor of 1.0.

PS: The directives to re-generate the tabulated coefficient functions should now be complete and I should also upload here the script to produce similar comparisons as above.

  • something is happening to some math symbols in your plot
  • by "Exact" you mean "exact matching", right? the thing you plot is still approximate ...

Yeah, that is some matplotlib thing that didn't bother to fix for the time being.

* by "Exact" you mean "exact matching", right? the thing you plot is still approximate ...

Yes. TBF, the label should be "NNPDF41@N3LO".

A new version v1.1.0 has just been released. I updated the description.
