Ascertain the supersymmetry breaking scale (superpartner mass scale)

Ascertain the energy scale at which supersymmetry is spontaneously broken, equivalently the characteristic superpartner mass scale often denoted m-tilde, given that current data do not fix this parameter and it can, in principle, range up to the Planck scale.

Background

In supersymmetric extensions of the Standard Model, superpartners acquire masses through SUSY breaking, introducing a characteristic mass scale (commonly denoted m-tilde). This scale controls collider phenomenology and the extent of electroweak fine-tuning, but remains unconstrained beyond existing experimental lower bounds.

The authors emphasize that without direct information on superpartner masses there is no way to fix the SUSY-breaking scale from first principles, leaving it as a free parameter that could, in principle, lie anywhere up to the Planck scale.

References

Without knowledge of the superpartner masses there is no way to know at what scale supersymmetry is spontaneously broken. Thus, it remains a free parameter.
