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.

关于F项问题和典型超对称破坏

受典型的典型F项问题的启发，我们强调了对有效模量的一般贡献，这种有效模量是由于模量和典型扇区之间的动力学混合而产生的。然后，我们将继续讨论一些具有这种效果的超重力玩具模型，并指出可能存在的缺点。有趣的是，在标准的2导数超重力作用中，没有术语来介导从动力学精粹区到高古尼区的超对称性破裂并产生马约拉纳质量。因此，我们还提出了一个2导数超对称不变量，该变量恰好发挥了这一作用。
