“…The one-loop RGEs for the MSSM-124 are presented in Appendix C.6. For many phenomenological analyses higher-loop accuracy is needed; see [57] for the full set of two-loop RGEs of the MSSM. Such scenarios are known as minimal flavor violation (MFV).…”

After an introduction recalling the theoretical motivation for low energy (100 GeV to TeV scale) supersymmetry, this review describes the theory and experimental implications of the soft supersymmetry-breaking Lagrangian of the general minimal supersymmetric standard model (MSSM). Extensions to include neutrino masses and nonminimal theories are also discussed. Topics covered include models of supersymmetry breaking, phenomenological constraints from electroweak symmetry breaking, flavor/CP violation, collider searches, and cosmological constraints including dark matter and implications for baryogenesis and inflation.

“…We work in the usual approximation where only the (3, 3) family components, y b , y t , y τ , of each Yukawa couplings matrix are important (for a review of these and other issues, see e.g. [16][17][18]). Concerning the Higgs sector, as common in this kind of phenomenological studies [19,20], we do not choose any specific model for (µ, Bµ), but we treat them as free parameters.…”

We evaluate the sparticle mass spectrum in the minimal four-dimensional construction that interpolates between gaugino and ordinary gauge mediation at the weak scale. We find that even in the hybrid case -when the messenger scale is comparable to the mass of the additional gauge particles -both the right-handed as well as the left-handed sleptons are lighter than the bino in the low-scale mediation regime. This implies a chain of lepton production and, consequently, striking signatures that may be probed at the LHC already in the near future.

We elucidate the physics underlying "anomaly mediation", giving several alternative derivations of the formulas for gaugino and scalar masses. We stress that this phenomenon is of a type familiar in field theory, and does not represent an anomaly, nor does it depend on supersymmetry breaking and its mediation. Analogous phenomena are common in QFT and this particular phenomenon occurs also in supersymmetric theories without gravity.

Two-loop renormalization group equations for soft supersymmetry-breaking couplings

Abstract: We compute the two-loop renormalization group equations for all soft supersymmetry-breaking couplings in a general softly broken N = 1 supersymmetric model. We also specialize these results to the minimal supersymmetric standard model.
