SUSY flavor structure of generic 5D supergravity models

, 2011
We perform a comprehensive and systematic analysis of the SUSY flavor structure of generic 5D supergravity models on S1/Z2 with multiple Z2-odd vector multiplets that generate multiple moduli.

CONSTRAINTS ON NO-SCALE SUPERGRAVITY MODELS

Modern Physics Letters A, 1995
We revisit the no-scale mechanism in the context of the simplest no-scale supergravity extension of the standard model. This model has the usual four-dimensional parameter space plus an additional parameter ξ3/2≡m3/2/m1/2. We show how predictions of the model may be extracted over the whole parameter space.

Keeping the relation between the Starobinsky model and no-scale supergravity ACTive

Journal of Cosmology and Astroparticle Physics
We introduce a modification of the Starobinsky model in the form of an additional cubic Ricci scalar curvature term ∼ αR 3, scaled by a dimensionless parameter α, with the resulting inflaton potential being the standard Starobinsky potential modified ...

Cosmological consequences of supergravity models

Second international workshop on particle physics and the early universe (COSMO-98), 1999
Gravity mediated supergravity models with H-parity invariance give rise naturally to a dark matter candidate, the lightest neutralino. Models with both universal soft breaking (mSUGRA) and with non-universal soft breaking (in the Higgs and third generation sectors) are shown to be consistent with the recent DAMA data suggesting the existence of an ...

Calculating the weak scale in supergravity models

Physical Review D, 1987
A renormalization framework is presented for calculating radiative SU(2) x U(1) gauge symmetry breaking in no-scale supergravity models. In this framework one naturally incorporates so-called threshold effects due to finite particle masses, without introducing an infrared cutoff scale.
