Higgs Messengers

Evans, Jason L., Sudano, Matthew, Yanagida, Tsutomu T.

Understand

We explore the consequences of the Higgs fields acting as messengers of supersymmetry breaking.

  • The hidden-sector paradigm in the gauge mediation framework is relaxed by allowing two types of gauge-invariant, renormalizable operators that are typically discarded: direct coupling between the Higgses and supersymmetry breaking singlets, and Higgs-messenger mixing terms.
  • The most important phenomenological consequence is a flavor-dependent shift in sfermion masses.
  • This is from a one-loop contribution, which we compute for a general set of weak doublet messengers.
