The impact of hidden sector renormalisation on estimates of fine tuning

Presented by Edward HARDY on 24 Jul 2014 from 14:30 to 14:50
Type: Formal SUSY and Strings
Track: Formal SUSY and Strings


The simplest models of supersymmetry compatible with LHC searches typically require very significant tuning of the electroweak scale. However, the renormalisation flow of the visible sector soft masses can be significantly modified by the dynamics of the hidden sector. I will discuss ways in which this can modify conventional estimates of the fine tuning, and show that if the hidden sector runs through a region of strong coupling not too far from the weak scale, a dramatic reduction in tuning is possible.
