Abstract

This paper completes the study of the next-to-leading-order QCD corrections to massive color-octet vector boson production at the LHC and Tevatron. The massive color-octet vector bosons are generically referred to as colorons. Building on our previous calculation of quark-initiated coloron production at next-to-leading order, we use the pinch technique to investigate coloron production via gluon fusion. We demonstrate that this one-loop production amplitude is finite and find that its numerical contribution to coloron production is typically 4 orders of magnitude smaller than the contribution from quark annihilation. Coloron production via gluon fusion is therefore relevant only if the colorons are (nearly) fermiophobic. We then present extensive plots and tables of our full results for next-to-leading-order coloron production at the Tevatron and the LHC.
