Superstring-inspired supergravity models [PDF]
We find an explicit and general formula for the Kahler potential of a broad class ofN=1 supergravity models based on symmetric spaces which exhibit a no-scale structure. Both the main features and the low-energy physics emerging from these models are studied. Their relevance, in the context of superstring theories, is also discussed.

CONSTRAINTS ON NO-SCALE SUPERGRAVITY MODELS
Modern Physics Letters A, 1995We 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.

Cosmological consequences of supergravity models
Second international workshop on particle physics and the early universe (COSMO-98), 1999Gravity 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, 1987A 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.
