MIT–CTP–2923 hep-ph/9911329 THE µ-PARAMETER OF SUPERSYMMETRY
ثبت نشده
چکیده
The Higgsino mass, or equivalently the µ-parameter, plays an essential role in determining the phenomenology of any supersymmetric model. Particularly, the size of the supersymmetry conserving µ-parameter must be correlated with the size of the soft supersymmetry breaking parameters. The source of this correlation in the underlying ultraviolet theory is one of the mysteries of supersymmetry model building. The puzzle and the various possibilities for its resolution are reviewed, stressing both phenomenological and theoretical aspects. New proposals in the context of supergravity and gauge-mediation frameworks for the soft supersymmetry breaking parameters are examined in some detail.

In the coming years, experiments underway will increase the sensitivity to charged lepton flavor violation by four orders of magnitude. These experiments will stringently probe weak scale physics. I review the status of global symmetries in the standard model and present several well-motivated models that predict observable lepton flavor violation. Finally, I describe what we might learn from f...
متن کامل00 2 Minimum Of QCD Effective Action As Test Of QCD Confinement Parameter
Recently (hep-ph/0109278), a modification A µ → B µ = (1 + µ∂ m)A µ for the gluon field A µ in the QCD Lagrangian (m = small gluon mass), yielded a k −4 behaviour for the gluon propagator, conventionally associated with linear confinement. This was prompted by a lack of consensus of results from other standard non-perturbative approaches on the T-dependence of gluon condensates in the cos-molog...
متن کاملGauge Messenger Models
We consider gauge messenger models in which X and Y gauge bosons and gauginos are messengers of supersymmetry breaking. In simple gauge messenger models, all the soft parameters except μ and Bμ are calculated in terms of a single scale parameter MSUSY which is proportional to F/MGUT. Unique prediction on dark matter in gauge messenger models is discussed. (Based on hep-ph/0601036 and hep-ph/060...

Most models of inflation have small parameters, either to guarantee sufficient inflation or the correct magnitude of the density perturbations. In this paper we show that, in supersymmetric theories with weak scale supersymmetry breaking, one can construct viable inflationary models in which the requisite parameters appear naturally in the form of the ratio of mass scales that are already prese...
