SUSY Breaking by Coexisting Walls ∗
نویسنده
چکیده
Supersymmetry (SUSY) breaking without messenger fields is proposed. We assume that our world is on a wall and SUSY is broken only by the coexistence of another wall with some distance from our wall. The Nambu-Goldstone (NG) fermion is localized on the distant wall. Its overlap with the wave functions of physical fields on our wall gives the mass splitting of physical fields thanks to a low-energy theorem. We propose that this overlap provides a practical method to evaluate mass splitting in models with SUSY breaking due to the coexisting walls. Parallel session talk at 8th International Symposium on Particles, Strings and Cosmology (PASCOS 2001), University of North Carolina at Chapel Hill, NC, USA, April 10-15, 2001.

Effective theory for wall-antiwall system
We propose a useful method for deriving the effective theory for a system where BPS and anti-BPS domain walls coexist. Our method respects an approximately preserved SUSY near each wall. Due to the finite width of the walls, SUSY breaking terms arise at tree-level, which are exponentially suppressed. A practical approximation using the BPS wall solutions is also discussed. We show that a tachyo...
متن کاملModeling a network of brane worlds
We study junctions of supersymmetric domain walls in N = 1 supergravity theories in four dimensions, coupled to a chiral superfield with quartic superpotential having Z3 symmetry. After deriving a BPS equation of the domain wall junction, we consider a stable hexagonal configuration of network of brane junctions, which are only approximately locally BPS. We propose a model for a mechanism of su...
متن کاملR-symmetry, supersymmetry breaking and metastable vacua in global and local supersymmetric theories
We study N = 1 global and local supersymmetric theories with a continuous global U(1)R symmetry as models of dynamical supersymmetry (SUSY) breaking. We introduce explicit R-symmetry breaking terms into such models, in particular a generalized O’Raifeartaigh model. Such explicit R-symmetry breaking terms can lead to a SUSY preserving minimum. We classify explicit R-symmetry breaking terms by th...
متن کاملDynamical Supersymmetry Breaking without Messenger Gauge Interactions
We investigate low-energy models of supersymmetry (SUSY) breaking by means of vector-like gauge theories for dynamical SUSY breaking. It is not necessary to introduce messenger gauge interactions utilized so far to mediate the SUSY breaking to the standard-model sector, which reduces complication in the model building. We also consider various other ways of SUSY-breaking transmission.
متن کاملPhenomenological Constraints on SUSY SU(5) GUTs with Non-universal Gaugino Masses
Supersymmetric gauge field theories are among the most promising models for physics beyond the standard model. The low-energy supersymmetry (SUSY) solves the so-called hierarchy problem, which basically follows from the tremendous scale differences in realistic models including gravity. After SUSY breaking, SUSY models, e.g. the minimal supersymmetric standard model (MSSM) have over hundred fre...
