چکیده

It is conjectured that M-theory in asymptotically flat spacetime must be supersymmetric, and that the observed SUSY breaking in the low energy world must be attributed to the existence of a nonzero cosmological constant. This would be consistent with experiment, if the critical exponent α in the relation MSUSY ∼ MP (Λ/M 4 P ) α took on the value 1/8 , rather than its classical value 1/4. We attribute this large renormalization to the effect of large virtual black holes via the UV/IR correspondence.

Dynamical supersymmetry breaking with a large internal dimension

Supersymmetry breaking in string perturbation theory predicts the existence of a new dimension at the TeV scale. The simplest realization of the minimal supersymmetric Standard Model in the context of this mechanism has two important consequences: (i) A natural solution to the µ-problem; (ii) The absence of quadratic divergences in the cosmological constant, which leads to a dynamical determina...

Realistic Cosmological Constant

Scenarios of supersymmetry breaking at various scales from TeV to GUT to the string are generated. A previous analysis generated the value of the experimentally measured cosmological constant from supersymmetry breaking at the TeV scale. Via a reorganization of the perturbative series, values of the cosmological constant are generically reconcilable with supersymmetry breaking scenarios having ...

Supersymmetry Breaking in Superstring Theory by Gaugino Condensation and its Phenomenology

The weakly-coupled heterotic string is known to have problems of dilaton/moduli stabilization, supersymmetry breaking (by hidden-sector gaugino condensation), gauge coupling unification (or the Newton’s constant), QCD axion, as well as cosmological problems involving dilaton/moduli and axion. We study these problems by adopting the point of view that they arise mostly due to our limited calcula...

Conformal Supersymmetry Breaking and Dynamical Tuning of the Cosmological Constant

We propose “conformal supersymmetry breaking” models, which tightly relate the conformal breaking scale (i.e. R-symmetry breaking scale) and the supersymmetry breaking scale. The both scales are originated from the constant term in the superpotential through the common source of the R-symmetry breaking. We show that dynamical tuning between those mass scales significantly reduces the degree of ...
