also exist in the MSSM and are not crucial here. The fields $\tilde W_R, \tilde W, \tilde B'$ and $\tilde g$ are the fermion superpartners of the third component of right-handed isospin, left-handed isospin, $B-L$ and color gauge bosons respectively. The $a_\nu$ is the soft trilinear analogue of $Y_\nu$ and is, therefore, also a three-by-three matrix in family space. The superpotential and Lagrangian are valid in the energy regime between the GUT scale and the TeV scale. Here we continue by analyzing physics at the TeV scale.

The notation for the VEVs of the fields phenomenologically allowed to acquire sizable VEVs is $$\label{vevs}
    \left< \tilde \nu^c_3 \right> \equiv \frac{1}{\sqrt 2} v_R, \ \ \left<\tilde \nu_i\right> \equiv \frac{1}{\sqrt 2} {v_L}_i, \ \
    \left< H_u^0\right> \equiv \frac{1}{\sqrt 2}v_u, \ \ \left< H_d^0\right> \equiv \frac{1}{\sqrt 2}v_d,$$ where $i=1,2,3$ is the generational index and $\tan \beta \equiv v_u/v_d$. The generation of a right-handed sneutrino superfield is not identifiable through its interactions, unlike a left-handed electron neutrino which couples to the electron through the $SU(2)_L$ gauge interactions. As a result, there is freedom to rotate the right-handed neutrino fields into any basis and specifically to a basis in which only one generation of right-handed sneutrino
