Addendum to "Low-energy phenomenology of some supersymmetric E6-breaking patterns."

Abstract

Using the techniques of our earlier work we analyze two additional patterns of supersymmetric ${\mathrm{E}}_{6}$-breaking patterns that pass through the intermediate group $\mathrm{SU}(5)\ifmmode\times\else\texttimes\fi{}{\mathrm{U}(1)}_{x}$. The results we obtain for these two patterns are similar to those obtained earlier. The predictions for the proton lifetime, electroweak mixing angle, and properties of the second $Z$ boson are given for each pattern.
