Spontaneous supersymmetry breaking in the two-dimensional N=1 Wess-Zumino model (1410.6665v1)
Published 24 Oct 2014 in hep-lat, hep-ph, and hep-th
Abstract: 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 the supersymmetry breaking phase transition. In the supersymmetry broken phase we observe the emergence of the Goldstino particle.
