Precision Calculations in Supersymmetric Theories

Figure 7

Running of the gauge couplings from the electroweak to the Planck scale from [51]. The discontinuity for 𝜇=𝜇_SUSY and 𝜇=𝜇_GUT is clearly visible. In panel (b) an enlargement of (a) for the region around 𝜇=𝜇_GUT is shown where for the decoupling the two values 𝜇_GUT=10^15.5 GeV ≈3.2⋅10¹⁵ GeV and 𝜇_GUT=10¹⁶ GeV have been chosen.
