Metastable supersymmetry breaking and multitrace deformations of SQCD

Essig, Rouven, Fortin, Jean-Francois, Sinha, Kuver et al.

Understand

Metastable vacua in supersymmetric QCD in the presence of single and multitrace deformations of the superpotential are explored, with the aim of obtaining an acceptable phenomenology.

  • The metastable vacua appear at one loop, have a broken R-symmetry, and a magnetic gauge group that is completely Higgsed.
  • With only a single trace deformation, the adjoint fermions from the meson superfield are approximately massless at one loop, even though they are massive at tree level and R-symmetry is broken.
  • Consequently, if charged under the standard model, they are unacceptably light.
