Triple Electroweak Gauge-Boson Production at Fermilab Tevatron Energies

Abstract

We calculate the three gauge-boson production in the Standard Model at Fermilab Tevatron energies. At $\sqrt{s}=2$ TeV in $p\bar{p}$ collisions, the cross sections for the triple gauge-boson production are typically of order 10 femtobarns (fb). For the pure leptonic final states from the gauge-boson decays and with some minimal cuts on final state photons, the cross sections for $p\bar{p}\to W^{\pm }\gamma \gamma ,Z\gamma \gamma$ and $W^{+}{W}^{-}\gamma$ processes are of order a few fb, resulting in a few dozen clean leptonic events for an integrated luminosity of 10 fb${}^{-1}$. The pure leptonic modes from other gauge-boson channels give significantly smaller rate. Especially, the trilepton modes from $W^{+}{W}^{-}{W}^{\pm }$ and $t\bar{t}{W}^{\pm }\to W^{+}{W}^{-}{W}^{\pm }$ yield a cross section of order 0.1 fb if there is no significant Higgs boson contribution. For a Higgs boson with $m_H^{}\simeq 2M_Z^{}$, the triple massive-gauge-boson production rate could be enhanced by a factor of $4-6$.
