The Supersymmetric R-Parity Violating Dine-Fischler-Srednicki-Zhitnitsky Axion Model

Understand

We propose a complete R-parity violating supersymmetric model with baryon triality that contains a Dine-Fischler-Srednicki-Zhitnitsky axion chiral superfield.

• We parametrize supersymmetry breaking with soft terms, and determine under which conditions the model is cosmologically viable.
• As expected we always find a region of parameter space in which the axion is a cold dark matter candidate.
• The mass of the axino, the fermionic partner of the axion, is controlled by a Yukawa coupling.
