2D SUPERGRAVITY WITH APPLICATIONS TO INTEGRABLE MODELS

Modern Physics Letters A, 1993
In recent work two different approaches for obtaining the covariant action of 2D quantum supergravity are developed. The first one is based on Hamiltonian reduction of flat OSP (2|1) connection in holomorphic polarization. Adding extra degrees of freedom with the help of gauging procedure, the action and the superconformal Ward identity are obtained ...

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.

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 ...
