Abstract

Using the most recent experimental data on parameters of the standard electroweak theory, as well as renormalisation group equations with a boundary matching condition, we derive a refined and more accurate value for the mass of the doubly-charged bilepton ($Y^{\pm\pm}$) occurring in the spontaneous breaking of the gauge group $SU(3)_L \times U(1)_X$ to the standard electroweak gauge group $SU(2)_L \times U(1)_Y$. Our result is $M(Y^{\pm\pm}) = (1.29 \pm 0.06)$ TeV.
