Gauge coupling unification

[MailQuestion]

Hi Florian,

Using SARAH, how can one check for gauge coupling unification in case of mSUGRA models with very large universal scalar mass m_0?

Thanks in advance,
Amin

Hi,

the easiest way is to generate a SPheno version and run it. By default, the scale g1=g2 is used as GUT scale, and the value of g3 at this scale is also printed in the output. So, you can check how big the difference between them is.

Cheers

Thank you Florian. This seems straightforward.
I am, however, using SOFTSUSY to generate the spectrum. I can change to SPheno of course, but just out of curiosity, I am wondering if you know whether SOFTSUSY prints out those couplings at the GUT scale? I can't seem to locate them in the output.
Thank you again.

Best,
Amin

No idea. I didn't run softsusy for quite some time.
