Description
We present a supersymmetric model where energy scales of a discrete R-symmetry breaking (Z6R) and cosmic inflation are commonly attributed to the confinement scale of a hidden Sp(2) strong dynamics. Apart from these, SUSY-breaking scale, the Higgsino mass and the right-handed neutrino masses are all shown to stem from Z6R breaking scale inferred from CMB observables. We will show that the model is characterized by the SUSY-breaking soft mass m~100-1000TeV and the reheating temperature T~10^{9}GeV. Then we discuss how these predictions of the model can be tested with the help of the spectrum of the gravitational wave induced by the short-lived cosmic string present during the reheating era.
