Asymptotic Padé Predictions up to Six Loops in QCD and Eight Loops in
J. A. Gracey, I. Jack, D. R. T. Jones
We assess the accuracy of our previous Asymptotic Padé predictions of the five-loop QCD -function and quark mass anomalous dimension in the light of subsequent exact results. We…
Bounds on scalar masses in two Higgs doublet models
P. M. Ferreira, D. R. T. Jones
A thorough analysis of stability and perturbativity bounds is performed in several versions of the two-Higgs doublet model, for both CP-conserving and spontaneously broken CP minim…
Anomaly Mediation, Fayet-Iliopoulos D-terms and the Renormalisation Group
R. Hodgson, I. Jack, D. R. T. Jones
We address renormalisation group evolution issues that arise in the Anomaly Mediated Supersymmetry Breaking scenario when the tachyonic slepton problem is resolved by Fayet-Iliopou…
Anomaly Mediation and Dimensional Transmutation
D. R. T. Jones, G. G. Ross
We show how a sparticle spectrum characteristic of anomaly mediation can arise from a theory whose Lagrangian contains no explicit mass scale. The scale of supersymmetry breaking i…
Four-loop beta function and mass anomalous dimension in Dimensional Reduction
R. V. Harlander, D. R. T. Jones, P. Kant +2
Within the framework of QCD we compute renormalization constants for the strong coupling and the quark masses to four-loop order. We apply the DR-bar scheme and put special emphasi…
Snowmass Benchmark Points and Three-Loop Running
I. Jack, D. R. T. Jones, A. F. Kord
We present the full three-loop beta-functions for the MSSM generalised to include additional matter multiplets in 5, 10 representations of SU(5). We analyse in detail the effect of…
Anomaly Mediated Supersymmetry Breaking, D-terms and R-symmetry
D. R. T. Jones
We explore two distinct resolutions to the tachyonic slepton puzzle in the Anomaly Mediated Supersymmetry Breaking scenario. Both are based on extending the MSSM by an anomaly free…
Renormalisation-group invariance and soft supersymmetry-breaking
I. Jack, D. R. T. Jones
We show that a particular ``universal'' form for the soft-breaking couplings in a softly broken supersymmetric gauge theory is renormalisation-group invariant through two loo…
