Comparison of SUSY spectra generators for natural SUSY and string landscape predictions

Abstract Models of natural supersymmetry give rise to a weak scale $$m_{weak}\sim m_{W,Z,h}\sim 100$$ m weak ∼ W , Z h 100 GeV without any (implausible) finetuning independent contributions the scale. These models, which exhibit radiatively driven naturalness (RNS), are expected arise from statistical analysis string landscape wherein large soft terms favored, but subject not-too-large value derived in each pocket universe greater multiverse. The picture then predicts, using Isajet SUSY spectra generator Isasugra, peak at $$m_h\sim 125$$ 125 with sparticles generally beyond current LHC search limits. In this paper, we investigate how well these conclusions hold up other popular generators: SOFTSUSY, SPHENO and SUSPECT (SSS). We built computer code DEW4SLHA operates on Les Houches Accord files calculate associated electroweak measure $$\Delta _{EW}$$ Δ EW . SSS generators tend yield Higgs mass $$\sim –127 superparticle rather similar that generated by Isasugra. an Appendix, include loop corrections more standard notation.
