Off-diagonal output

Hi,
I am trying to get out put of SM+ YN H.l.vR model. Here Yn is 3X3 Yukwa type matrix. All 9 terms are non-zero (may be complex). I want 9 RGEs for these Yn. But I got only three RGEs for the diagonal terms. Do there have any command(s) in this regards.
Please help me.

Hi,
I just tried it myself, and get at one-loop
Code: Select all
{Yv[i1, i2], ((-9*g1^2)/20 - (9*g2^2)/4 + 3*trace[Yd, Adj[Yd]] +
trace[Ye, Adj[Ye]] + 3*trace[Yu, Adj[Yu]] +
trace[Yv, Adj[Yv]])*Yv[i1, i2] -
(3*(MatMul[Yv, Adj[Ye], Ye][i1, i2] - MatMul[Yv, Adj[Yv], Yv][
i1, i2]))/2, 0}
That looks actually fine to me.
Cheers,
Florian

Thanks for the reply.
I got the same. But in solution of RGEs file "RunRGEs.m" I got only three RGEs for Yv term, i.e., Yv[1,1], Yv[2,2] and Yv[3,3].

Yes, the Mathematica code to run the RGEs includes by default only diagonal terms. You can change this by setting
Code: Select all
SetOptions[PrepareRGEs,OnlyDiagonal->False]
before running CalcRGEs. However, you have to be prepare that the numerical evaluation within Mathematica will become very slow.
