Finite-Temperature Supersymmetry: The Wess-Zumino Model
We investigate the breakdown of supersymmetry at finite temperature. While it has been proven that temperature always breaks supersymmetry, the nature of this breaking is less clear. On the one hand, a study of the Ward-Takahashi identities suggests a spontaneous breakdown of supersymmetry without the existence of a Goldstino, while on the other hand it has been shown that in any supersymmetric...
متن کاملStudy of dynamical supersymmetry breaking for the two dimensional lattice Wess - Zumino model
A new approach to the study of the transition point in a class of two dimensional WessZumino models is presented. The method is based on the calculation of rigorous lower bounds on the ground state energy density in the infinite lattice limit. Such bounds are useful in the discussion of supersymmetry phase transition. The transition point is then determined and compared with recent results base...
متن کاملComposite Operators, Supersymmetry Anomalies and Supersymmetry Breaking in the Wess-Zumino Model
A possible mechanism for supersymmetry breaking is that it is broken by a host of supersymmetry anomalies that occur in composite operators. These anomalies are well hidden. This paper explains where they may be found. Using a source φα to absorb the free spinor index, it is shown that the simplest, potentially anomalous, composite spinor operator has the form: A (0) φ = ∫ dx φf j i { Γ i AjCα ...
متن کاملSpontaneous supersymmetry breaking in the 2D N=1 Wess-Zumino model.
We study the phase diagram of the two-dimensional N=1 Wess-Zumino model on the lattice using Wilson fermions and the fermion loop formulation. We give a complete nonperturbative determination of the ground state structure in the continuum and infinite volume limit. We also present a determination of the particle spectrum in the supersymmetric phase, in the supersymmetry broken phase and across ...
متن کاملDynamical supersymmetry breaking and phase diagram of the lattice Wess-Zumino model
We study dynamical supersymmetry breaking and the transition point by non-perturbative lattice techniques in a class of two-dimensional N = 1 Wess-Zumino model. The method is based on the calculation of rigorous lower bounds on the ground state energy density in the infinite-lattice limit. Such bounds are useful in the discussion of supersymmetry phase transition. The transition point is determ...
