High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is needed when higher-order corrections are included. We propose such a scheme, Supersymmetry Parameter Analysis SPA, based on a consistent set of conventions and input parameters. A(More)
The neutralino-proton cross section is examined for supergravity models with R-parity invariance with universal and non-universal soft breaking. The region of parameter space that dark matter detectors are currently (or will be shortly) sensitive i.e. (0.1 − 10) × 10 −6 pb, is examined. For universal soft breaking (mSUGRA), detectors with sensitivity σ ˜ χ(More)
We consider here the constraints in SUGRA models on the SUSY parameter space due to current experimental bounds on the light Higgs mass m h , the b → sγ decay, the amount of neutralino cold dark matter Ωh 2 , and the muon magnetic moment. Models with universal soft breaking (mSUGRA) and non-universal gaugino or Higgs masses at M G are examined. For mSUGRA,(More)
A general analysis of squeezing transformations for two mode systems is given based on the four dimensional real symplectic group Sp(4, ℜ). Within the framework of the unitary metaplectic representation of this group, a distinction between compact photon number conserving and noncompact photon number nonconserving squeezing transformations is made. We(More)
The electron electric dipole moment (d e) and the muon magnetic moment anomaly (a µ) recently observed at BNL are analyzed within the framework of SUGRA models with CP violating phases at the GUT scale. It is seen analytically that even if d e were zero, there can be a large Bino mass phase (ranging from 0 to 2π) with a corresponding large B soft breaking(More)
