Slepton flavor mixing and neutrino masses

“…for (i, ii) or (iii). These bounds have to be contrasted with the present experimental limit on the flavour changing masses coming from µ → eγ decay which reads δ l 12 < ∼ 10 −2 (m/100GeV ) 2 [12,13]. Thus, our considerations put for some of the textures much stronger bounds, which are insensitive to the values ofm i .…”

“…Indeed, our discussion to be more predictive, requires some theoretical framework for the soft sfermion masses departing from universality. As an example we take a supersymmetric SO(10) model with universal soft terms assumed at the Planck scale [13]. In this framework, the large top (neutrino) Yukawa coupling induces sfermion flavour mixing and a splitting of the third generation sfermion masses from the first two, due to RG effects from the Planck scale to the unification scale.…”

“…In this framework, the large top (neutrino) Yukawa coupling induces sfermion flavour mixing and a splitting of the third generation sfermion masses from the first two, due to RG effects from the Planck scale to the unification scale. This applies also to the left-handed sleptons which have the mass matrix in the flavour basis [12,13];…”

Results and perspectives in HEP, vis-a-vis lattice QCD

“…m c /m s = 8.23 ± 1.5 (26) Barbieri, Hall and Romanino [29] obtained the results given in fig. 2 for ρ + iη.…”

“…Relations of this type emerge naturally, for example, in hierarchical U (2) models for the flavour Figure 2. Confidence-level profiles for ρ+iη [29]. The smaller regions incorporate the constraints given by the quark-mass relations in eqs.…”
