| الوصف: | A new supergravity D-term, not associated to gauged R-symmetry, was recently discovered and used to construct new supergravity models. In this paper we use a generalization of the new D-term that we used in previous works, to construct a supergravity model of slow-roll inflation with the observable sector of the minimal supersymmetric standard model. Supersymmetry is broken at a high scale in the hidden sector and communicated to the observable sector by gravity mediation. The new D-term contains free parameters that can give large masses to scalar superpartners of quarks and leptons and to the higgsinos while holding the masses of observed particles fixed. Gauginos receive a mass from a non-canonical kinetic term for the vector supermultiplets. We also present a simple argument proving in full generality that the cutoff $\Lambda$ of effective theories containing new D-terms can never exceed the supersymmetry breaking scale. In our theory, the relation between D-term and the Hubble constant during inflation also implies the universal relation $\Lambda \lesssim \sqrt{H M_{Pl}}$. Comment: 30 pages. Another misspelling has been corrected. Accepted for publication in PRD. arXiv admin note: text overlap with arXiv:2206.13736 |
