Non-Degenerate Squarks from Flavored Gauge Mediation

Understand

We study the squark spectra of Flavored Gauge Mediation Models, in which messenger-matter superpotential couplings generate new, generation-dependent contributions to the squark masses.

• The new couplings are controlled by the same flavor symmetry that explains the fermion masses, leading to excellent alignment of the quark and squark mass matrices.
• This allows for large squark mass splittings consistent with all flavor bounds.
• In particular, second-generation squarks are often significantly lighter than the first-generation squarks.
