Introduction— meta-stable SUSY breaking Dynamical SUSY breaking  hierarchy problem can be solved Witten index  highly constrained models are allowed  very restricted models are considered before the discovery of the ISS model Witten index never restrict the possibility of meta- stable SUSY breaking vacua [Intriligator-Seiberg-Shih (2006)]

Plan of this talk Introduction Spontaneously broken N=2 SQCD Quantum theory Local minimum – numerical analysis Possible application to phenomenology Summary and future works

Spontaneous broken N=2 SQCD gauge theory with hypermultiplets and FI-term (D-term) The simplest case  Global symmetry

Pseudo flat direction Solution of stationary condition of the potential SUSY is broken at tree-level Pseudo flat direction Gauge symmetry U(1)_R is broken

Quantum theory Effective action FI term is tree-level exact [Arai-Kitazawa (1999)] Harmonic superspace analysis, gauge symmetry, U(1)_R charge…. Coulomb branch U(1) gauge theory  cutoff theory, Landau pole Seiberg-Witten analysis, Long-lived local minimum [Arai-Okada (2001)]

SUSY effective action Vector multiplet part Light BPS states around singular points M corresponds to dyons, monopoles, quarks Spinor representation of [Seiberg-Witten (1994)]

Prepotential Moduli space Monodoromy transf.  subgroup of Same structure with massive SQCD (common quark hypermultiplet mass) is regarded as the mass

Potential Stationary points  Singular points : energetically favored !

Solution SW curve Meromorphic differential Periods

Explicit form (Weierstrass functions, elliptic integrals)

U(1) sector

Local mininum Flow of singularities

Dyon points Increasing direction Re(a_1) direction

Im(a_1) direction

Local mininum at a_1 = 0 Local minimum at SUSY and global U(1)_R are broken !

Local minimum SUSY breaking and U(1)_R breaking Runaway direction

Decay rate estimate Long-lived vacuum [Dancan-Jensen (1992)]

Application to phenomenology SUSY breaking effect  gauge mediation Messenger sector Gaugino mass Singular point in moduli space (meta-stable vacuum)

Summary gauge theory with hypermultiplets and FI-term We have found a meta-stable vacuum in which SUSY and U(1)_R are dynamically broken (non-perturbative) Long-lived local minimum with runaway SUSY vacuum The model naturally contains messenger sector of gauge mediation

Future works Generalize to arbitrary Geometric realization of the meta-stable vacua : NS5/D4/(D6)  M5 (with TN) Embedding the Standard Model gauge symmetry into the flavor symmetry Finite temperature correction
