- my current understanding is that the M scheme is defined by [1, Eq. (2.12)]
- whether that equation also hold for OME I don't know, but given that this relation is introduced at such a "high" level I expect it to be universal
- we know from [1, below Eq. (2.17)]
$z_{gg} = z_{qg} = 0$ so I wonder if there is any additional transformation needed. To be specific: if OMEs follow a similar transformation as splitting functions (which might be reasonable) we can conclude from [1, Eq. (2.19)] that$A_{gg,M}^2= A_{gg,L}^2$

Actually we might have some more hints. By looking at eq 85 and 86 of [1], you can see that they are as
eq 26 and 27 of [2], apart of a factor 4 \beta_0
?!?
Unfortunately the transformation of A_qqNS
is not written explicitly.
So there are good chances that A_gg
transforms under an identity
but for according to Kay Schönwald A_{gq}
is not correct.
