We present a five dimensional supersymmetric SO(10) model compactified on an orbifold S/Z2 ×Z ′ 2. The gauge symmetry G422 ≡ SU(4)c×SU(2)L×SU(2)R, realized on one of the fixed points (branes), is spontaneously broken to the MSSM via the higgs mechanism. Employing a flavor U(1) symmetry and suitably extending the ’matter’ sector enables us to understand large mixings in the neutrino sector via a...

We present an update of previous work on charged lepton flavor violation (LFV) in the seesaw model. The most recent neutrino data fits and post WMAP mSUGRA benchmark scenarios are used as input. In this framework we compare the sensitivity of rare radiative decays on the right-handed Ma-jorana mass scale M R with the reach in slepton-pair production at a future linear collider.
