Heavy QQ(bar) "Fireball" Annihilation to Multiple Vector Bosons

Abstract

Drawing analogy of replacing the nucleon by heavy chiral quark $Q$, the pion by Goldstone boson $G$, and $\pi NN$ coupling by $GQQ$ coupling, we construct a statistical model for $Q\bar{Q}\to nG$ annihilation, i.e. into $n$ longitudinal weak bosons. This analogy is becoming prescient since the LHC direct bound $m_Q>611$ GeV implies strong Yukawa coupling. Taking $m_Q\in (1,2)$ TeV, the mean number $<n_G>$ ranges from 6 to over 10, with negligible two or three boson production. With individual $t^{\prime }$ or $b^{\prime }$ decays suppressed either by phase space or quark mixing, and given the strong Yukawa coupling, $Q\bar{Q}\to n{V}_L$ is the likely outcome for very heavy $Q\bar{Q}$ production at the LHC.
