All deviations from alignment in this mass matrix are gathered in the $\d$ matrices, which contain 30 real parameters (including 12 phases) and are defined as: m\^2\_[LL]{}=m\_L\^2 ( + \^[LL]{} ) & &m\^2\_[RR]{}=m\_R\^2 ( + \^[RR]{} )\

The supersymmetric contributions to $d_i$, $(i=e,\mu,\tau)$, can be splitted in two parts, involving respectively only flavour conserving (FC) or flavour violating (FV) elements of the slepton mass matrix (\[sleptonm2\]): d\_i = d\_i\^[FC]{} +d\_i\^[FV]{} d\_i\^[FC]{} &= & \[ m\_i [I]{}m() ( I\_B + I\_L - I\_R + I\_2 ) - v\_d [I]{}m(A\_[ii]{}\^\*) I\_B \] \[FC\]\
