Lepton Flavour Violation in charged leptons within SUSY-seesaw
Abstrak
In this paper we review our main results for Lepton Flavour Violating (LFV) semileptonic tau decays and muon-electron conversion in nuclei within the context of two Constrained SUSY-Seesaw Models, the CMSSM and the NUHM. The relevant spectrum is that of the Minimal Supersymmetric Standard Model extended by three right handed neutrinos, ν R i and their corresponding SUSY partners, ν ˜ R i , ( i = 1 , 2 , 3 ) . We use the seesaw mechanism for neutrino mass generation and choose a parameterisation of this mechanism that allows us to incorporate the neutrino data in our analysis of LFV processes. In addition to the full one-loop results for the rates of these processes, we will also review the set of simple formulas, valid at large tan β , which are very useful to compare with present experimental bounds. The sensitivity to SUSY and Higgs sectors in these processes will also be discussed. This is a very short summary of the works in Refs. [E. Arganda, M. J. Herrero and J. Portoles, JHEP 0806 (2008) 079 [ arXiv:0803.2039 [hep-ph] ]] and [E. Arganda, M. J. Herrero and A. M. Teixeira, JHEP 0710 (2007) 104 [ arXiv:0707.2955 [hep-ph] ]] to which we refer the reader for more details.
