A model of electroweak interactions is presented in which quarks transform the quark-matter electroweak symmetry ${G}^{q}={\mathrm{SU}(2)}_{L}^{q}\ifmmode\times\else\texttimes\fi{}{\mathrm{U}(1)}_{Y}^{q}$ and leptons transform under the leptonic-matter electroweak symmetry ${G}^{l}={\mathrm{SU}(2)}_{L}^{l}\ifmmode\times\else\texttimes\fi{}{\mathrm{U}(1)}_{Y}^{l}$. The standard electroweak interactions are the diagonal sum of ${G}^{q}\ifmmode\times\else\texttimes\fi{}{G}^{l}$ interactions resulting from spontaneous symmetry breaking. In this model the charged and neutral bosons behaving like the $W$ and $Z$ of the standard model have mass lower bounds of order 1 TeV while there exists the possibility of an additional massive neutral boson with mass as low as 150 GeV.
