New Derivation of Anomaly-Mediated Gaugino Mass in the Higher Derivative Regularization Method
نویسندگان
چکیده
The technique of higher derivative regularization is applied to the Super-WeylKähler anomaly in supergravity coupled with chiral matters and gauge multiplet. Our method makes it possible to derive directly and diagrammatically the formulae for the gaugino mass (in the Abelian case). Our procedure is applied to derivation of not only the mass formulae known in the anomaly mediation scenario, but also additional terms that depend on the Kähler potential. ∗) e-mail:[email protected] ∗∗) e-mail:[email protected] 1 §

The Supersymmetric Kink via Higher-Derivative and Momentum Cut-Off Regularization Schemes
We study the supersymmetric kink with higher derivative and momentum cut-off regularization schemes. We introduce the new momentum cut-off regularization scheme which we call “generalized momentum cut-off”. A new, explicit computation for the central charge anomaly for this scheme is described in detail. The calculation of the first order mass corrections for the bosonic and supersymmetric kink...
متن کاملAnomaly Mediation in Supergravity Theories
We consider the effects of anomalies on the supersymmetry-breaking parameters in supergravity theories. We construct a supersymmetric expression for the anomalyinduced terms in the 1PI effective action; we use this result to compute the complete one-loop formula for the anomaly-induced gaugino mass. The mass receives contributions from the super-Weyl, Kähler, and sigma-model anomalies of the su...
متن کاملOne loop soft supersymmetry breaking terms in superstring effective
We perform a systematic analysis of soft supersymmetry breaking terms at the one loop level in a large class of string effective field theories. This includes the so-called anomaly mediated contributions. We illustrate our results for several classes of orbifold models. In particular, we discuss a class of models where soft supersymmetry breaking terms are determined by quasi model independent ...
متن کاملVacuum stability bounds in Anomaly and Gaugino Mediated SUSY breaking models
We constrain the parameter space of the minimal and gaugino–assisted anomaly mediation, and gaugino mediation models by requiring that the electroweak vacuum corresponds to the deepest minimum of the scalar potential. In the framework of anomaly mediation models we find strong lower bounds on slepton and squark masses. In the gaugino mediation models the mass spectrum is forced to be at the TeV...
متن کاملNon-diagrammatic calculation of QCD one-loop β-function based on the exact renormalization group equation
Using the higher covariant derivatives and gauge invariant Pauli-Villars regularization of gauge theories in the framework of the background field method, we obtain a version of the exact renormalization group equation for the regulator fields, whose vacuum energy depends on the background gauge field. It is evaluated using an anomalous Ward-Takahashi identity, which is related to the rescaling...
