Refined Mass Estimate for Bilepton Gauge Boson

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.
