Direct Mediation , Duality and Unification

  title={Direct Mediation , Duality and Unification},
  author={Steven Abel and Valentin V. Khoze},
It is well-known that in scenarios with direct gauge mediation of supersymmetry breaking the messenger fields significantly affect the running of Standard Model couplings and introduce Landau poles which are difficult to avoid. Among other things, this appears to remove any possibility of a meaningful unification prediction and is often viewed as a strong argument against direct mediation. We propose two ways that Seiberg duality can circumvent this problem. In the first, which we call… CONTINUE READING
