Title : Colored Resonances at the Tevatron: Phenomenology and Discovery
Potential in Multijets
Abstract:
There exist several classes of theories beyond the Standard Model which contain massive spin-1 color-octet particles, generically called "colorons". Indeed we argue that colorons inevitably appear in the spectrum whenever new colored particles feel an additional confining force. Colorons are distinctive at hadron colliders as this is the only environment in which they can be resonantly produced. In the simplest models we show that the coloron naturally decays to multijets via secondary resonances, which can be consistent with all existing bounds, even for colorons as light as a few hundred GeV. We perform a representative case study and show that a search in the four-jet channel at the Tevatron has strong signal significance, while the LHC faces formidable challenges for such a search. |
