# Plot of gauge coupling unification [closed]

(Zoom in here to see the scales.)
About the result of plotting running of 3 coupling constant, we think that we should get the correct one(MSSM).

But we get discontinuity at $M_{susy}$.

If there something wrong in our formulae? If you have the correct formulae of $1/\alpha$, please provide them for me.

Hi, you can find the full 2-loop beta functions in Martin and Vaughn here: arxiv.org/abs/hep-ph/9311340 –  sujeet Jun 10 '13 at 5:41
I can't read the scales on your plot well enough to see whether they are different. –  Michael Brown Jun 10 '13 at 6:40
