  The ttbar asymmetry measured at the Tevatron continues to disagree with
Standard Model predictions at the 3 sigma level. We update the status of the
phenomenological light axigluon model in explaining the asymmetry data, taking
into account constraints from the charge asymmetry at the LHC and the ttbar
cross section at both Tevatron and LHC. We find that an axigluon with a mass
between 100 and 400 GeV provides an excellent fit to the data. Recent searches
by ATLAS and CMS for pair production of heavy resonances which decay to dijets
rule out axigluons with large branching fractions to dijets. However axigluons
which predominantly decay to multijets via intermediate resonances are still a
possibility. We outline four distinct scenarios which cover the most important
decay topologies and discuss how one might exclude or discover axigluons as
multijet resonances at the LHC. MadGraph implementations for each of the
scenarios are provided.
