Dynamical supersymmetry breaking in theories without Lagrangians
نویسندگان
چکیده
We demonstrate that the supersymmetry can be dynamically broken even in theories without a Lagrangian. The example we study is the four-dimensional SUðNÞ gauge theory coupled to a strongly coupled superconformal theory, called TN , which does not have a Lagrangian description at present. Such a theory without Lagrangians can be analyzed due to the supersymmetry and duality. The model is a direct generalization of the model of supersymmetry breaking on deformed moduli space in supersymmetric QCD with an SU(2) gauge group.

Composite Quarks and Leptons from Dynamical Supersymmetry Breaking without Messengers
We present new theories of dynamical supersymmetry breaking in which the strong interactions that break supersymmetry also give rise to composite quarks and leptons with naturally small Yukawa couplings. In these models, supersymmetry breaking is communicated directly to the composite fields without “messenger” interactions. The compositeness scale can be anywhere between 10 TeV and the Planck ...
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 کاملRecent Developments in Dynamical Supersymmetry Breaking
Some formal aspects of supersymmetry breaking are reviewed. The classic " requirements " for supersymmetry breaking include chiral matter, a dynamical su-perpotential, and a classical superpotential which completely lifts the moduli space. These " requirements " may be evaded in theories with large matter representations. The mechanisms of supersymmetry breaking by confinement and quantum defor...
متن کاملDynamical Supersymmetry Breaking and Low Energy Gauge Mediation
Dynamical breaking of supersymmetry was long thought to be an exceptional phenomenon, but recent developments have altered this view. A question of great interest in the current framework is the value of the underlying scale of supersymmetry breaking. The “little hierarchy” problem suggests that supersymmetry should be broken at low energies. Within one class of models, low energy breaking be a...
متن کاملAn Introduction to Dynamical Supersymmetry Breaking
We present an introduction to dynamical supersymmetry breaking, highlighting its phenomenological significance in the context of 4D field theories. Observations concerning the conditions for supersymmetry breaking are studied. Holomorphy and duality are shown to be key ideas behind dynamical mechanisms for supersymmetry breaking, with attention paid to supersymmetric QCD. Towards the end we dis...
