Key Points

  • The aim is to investigate chiral symmetry breaking minima in supersymmetric symplectic QCD under AMSB.
  • Analyze chiral symmetry breaking minima in supersymmetric symplectic QCD.
  • Focus on theories with different numbers of flavors (Nf) relative to colors (Nc).
  • Evaluate the potential minima and their stability under AMSB conditions.
  • All Sp(Nc) theories where AMSB applies have stable chiral symmetry breaking minima.
  • For Nf = Nc + 1, careful analysis is needed due to strong coupling.
  • Minima are potentially connected to vacua of QCD-like theories with significant SUSY breaking.

Abstract

A bstract We present a careful study of the chiral symmetry breaking minima and other potential minima in supersymmetric symplectic QCD (Sp( N c ) with N f flavors) perturbed by Anomaly Mediated Supersymmetry Breaking (AMSB). Although the case of N f = N c + 1 requires particular care due to the inherently strongly coupled nature of the quantum modified moduli space, we are able to show that all Sp( N c ) theories to which AMSB can be applied ( N f < 3( N c + 1)) possess stable chiral symmetry breaking minima, which are plausibly continuously connected to the vacua of QCD-like Sp( N c ) theories for large SUSY breaking, and are protected from runaways to incalculable minima.
