# Renormalization group invariants in the MSSM and its extensions

@article{Demir2004RenormalizationGI, title={Renormalization group invariants in the MSSM and its extensions}, author={Durmuş Demir}, journal={Journal of High Energy Physics}, year={2004}, volume={2005}, pages={003-003} }

We derive one-loop renormalization group (RG) invariant observables and analyze their phenomenological implications in the MSSM and its µ problem solving extensions, U(1) ′ model and NMSSM. We show that there exist several RG invariants in the gauge, Yukawa and soft-breaking sectors of each model. In general, RG invariants are highly useful for projecting experimental data to messenger scale, for revealing correlations among the model parameters, and for probing the mechanism that breaks…

The minimal supersymmetric standard model as well as the renormalization group equations of its parameters are summarized and it is found that for the models in which global supersymmetry breaking arises slowly from soft gaugino masses and bilinear mixing between the two Higgs scalars the top quark mass can be nomore lighter than 180 GeV.
