Inflation and Supersymmetry Breaking
We study the connection between inflation and supersymmetry breaking in the context of an O’Raifeartaigh model which can account for both hybrid inflation and a true vacuum where supersymmetry is spontaneously broken. For a weakly coupled inflaton field, the dynamics during the inflationary phase can be determined by the supersymmetry breaking scale MS ∼ 1010 GeV, even if HI ≫ m3/2. The spectru...
متن کاملA Signature of Inflation from Dynamical Supersymmetry Breaking
In models of cosmological inflation motivated by dynamical supersymmetry breaking, the potential driving inflation may be characterized by inverse powers of a scalar field. These models produce observables similar to those typical of the hybrid inflation scenario: negligible production of tensor (gravitational wave) modes, and a blue scalar spectral index. In this short note, we show that, unli...
متن کاملSupersymmetry-Breaking Models of Inflation
We consider dynamical models of supersymmetry breaking which naturally incorporate cosmological inflation. The inflaton plays an inevitable role in dynamical SUSY breaking and the hierarchical scales of inflation and SUSY breaking are simultaneously realized through a single dynamics.
متن کاملDynamical Supersymmetry Breaking
We review mechanisms of dynamical supersymmetry breaking. Several observations that narrow the search for possible models of dynamical supersymmetry breaking are summarized. These observations include the necessary and sufficient conditions for supersymmetry breaking. The two conditions are based on non-rigorous arguments, and we show examples where they are too restrictive. Dynamical effects p...
متن کاملDynamical Supersymmetry Breaking
The ratio of the weak scale to the Planck scale, mW /mPl ∼ 10 , suggests that it should have a dynamical origin. Had this ratio been, e.g., ∼ 10 we would have suspected that the weak scale is a perturbative effect. In fact this ratio is of the right size for a nonperturbative effect in field theory. Had it been extremely small, e.g. ∼ 10 10 or so, we would have to look for some really exotic, u...
