Fine Tuning in General Gauge Mediation

Understand

We study the fine-tuning problem in the context of general gauge mediation.

• Numerical analyses toward for relaxing fine-tuning are presented.
• We analyse the problem in typical three cases of the messenger scale, that is, GUT ($2\times10^{16}$ GeV), intermediate ($10^{10}$ GeV), and relatively low energy ($10^6$ GeV) scales.
• In each messenger scale, the parameter space reducing the degree of tuning as around 10% is found.
