How conventional measures overestimate electroweak fine-tuning in supersymmetric theory

Understand

The lack of evidence for superparticles at the CERN LHC, along with the rather high value of the Higgs mass, has sharpened the perception that supersymmetric model parameter space is highly electroweak fine-tuned (EWFT).

• We compare three measures of fine-tuning in SUSY models.
• 1.
• \Del_HS measures a terms containing large log contributions to m_Z that are inevitable in models defined at scales much higher than the electroweak scale.
