On the F-term problem and quintessence supersymmetry breaking

Inspired by the stringy quintessence F-term problem we highlight a generic contribution to the effective moduli masses that arises due to kinetic mixings between the moduli and the quintessence sector. We then proceed to discuss few supergravity toy models that accommodate such effect, and point out possible shortcomings. Interestingly, in the standard 2-derivative supergravity action there is no term to mediate the supersymmetry breaking from the kinetic quintessence sector to the gaugini and generate Majorana masses. Therefore we also propose a 2-derivative supersymmetric invariant that plays exactly this role.

Automated summary

Inspired by the stringy quintessence F-term problem, we discuss a generic contribution to effective moduli masses arising from kinetic mixings. Several supergravity toy models accommodate this effect but may have shortcomings. A proposed 2-derivative supersymmetric invariant plays a crucial role in mediating supersymmetry breaking from the kinetic quintessence sector.
