The mass of pseudoscalar Higgs

[Dris]

Hi Florian,

How can explain the deference between m_A in the input and m_A in the output (e.g. 449 GeV and 213 GeV, respectively).

Best,

Dris.

Loop corrections

Thanks a lot,

How about the fact that is a O(100%) correction.

If you go to extreme regions of the parameter point this can happen: e.g., for tan\beta ~ 1 and super heavy stops the entire light Higgs mass is only generated via radiative corrections while it is approximately zero at tree-level.
What you should compare are one- and two-loop masses (if available; at the moment only for SUSY models in SARAH) to see how well perturbation theory converges and what the remaining uncertainty is.

Cheers,
Florian

The input and output spectrum have been sent to your email because I could not attach them, take a look on them please.

Best regards,
Dris.

Your value of tan\beta of ~63 is huge, i.e. the bottom Yukawa is as large as the top one. Therefore, you get for instance large corrections to m_Hd2 as you can see here

Code: Select all

Block TREEMSOFT Q=  1.00000000E+03  # (SUSY Scale)
  21    3.08291394E+04  # mHd2
  22   -1.78936277E+05  # mHu2
Block LOOPMSOFT Q=  1.00000000E+03  # (SUSY Scale)
  21   -3.64573714E+04  # mHd2
  22   -1.60014712E+05  # mHu2

Thanks a lot for this clarify.
