“…We list the renormalisation group equations (RGE) of the MSSM [57][58][59] and the MSSM with right-handed neutrinos [52,60,61] in Appendix C. The right-handed neutrinos are singlets under the SM gauge group so that they do not change the RGE for gauge couplings and gaugino masses. The procedure of solving the RGE is schematically depicted in Figure 11.…”

We derive new constraints on the quantities delta_{XY}^{ij}, X,Y=L,R, which parametrise the flavour-off-diagonal terms of the charged slepton mass matrix in the MSSM. Considering mass and anomalous magnetic moment of the electron we obtain the bound |delta^{13}_{LL} delta^{13}_{RR}|<0.1 for tan beta=50, which involves the poorly constrained element delta^{13}_{RR}. We improve the predictions for the decays tau -> mu gamma, tau -> e gamma and mu -> e gamma by including two-loop corrections which are enhanced if tan beta is large. The finite renormalisation of the PMNS matrix from soft SUSY-breaking terms is derived and applied to the charged-Higgs-lepton vertex. We find that the experimental bound on BR(tau -> e gamma) severely limits the size of the MSSM loop correction to the PMNS element U_{e3}, which is important for the proper interpretation of a future U_{e3} measurement. Subsequently we confront our new values for delta^{ij}_{LL} with a GUT analysis. Further, we include the effects of dimension-5 Yukawa terms, which are needed to fix the Yukawa unification of the first two generations. If universal supersymmetry breaking occurs above the GUT scale, we find the flavour structure of the dimension-5 Yukawa couplings tightly constrained by mu -> e gamma.Comment: 37 pages, 15 figures; typo in Equation (35) and (49) correcte

We investigate the validity of an idea that the B µ problem is solvable via the renormalization effect in the strongly interacting hidden sector within the gauge mediated supersymmetry breaking scenario. Our analysis starts with a naive boundary condition, which is that the squared scalar masses experience 16π 2 suppression. We use softsusy to get the low energy spectra of superparticles with the boundary condition at the scale (Λ CF T ) where the hidden sector is integrated out. We visit the low energy spectra and return to Λ CF T where the boundary conditions are given. We find that there is a sign problem, which seems to be generic.Keywords: MSSM, µ problem in GMSB, RG effect of the Hidden Sector.
