Description
Certain supersymmetric grand unified models predict
that the coefficients of the quadratic terms in the MSSM
Higgs potential should be degenerate at the GUT scale.
We discuss some examples for such models, and we
analyse the implications of this peculiar condition of a
GUT-scale degenerate Higgs mass matrix for low-scale
MSSM phenomenology. To this end we explore the
parameter space which is consistent with existing
experimental constraints by means of a Markov Chain
Monte Carlo analysis. This talk is based on
arXiv:1007.0321 and JHEP 0908:011.
