Color octet (pseudo)scalars, if they exist, will be copiously produced at the CERN Large Hadron Collider (LHC). However, their detection can become a very challenging task. In particular, if their decay into a pair of top quarks is kinematically forbidden, the main decay channel would be into two jets, with a very large background. In this brief report we explore the possibility of using anomaly-induced decays of the color octet pseudoscalars into gauge bosons to find them at the LHC.

Hadronically decaying color-adjoint scalars at the LHC
We study the phenomenology of the pair-production of scalar color-octet electroweak singlet states at the LHC. Such states appear in many extensions of the Standard Model. They can be pair-producedExpand
Lepton number violation from colored states at the LHC
The possibility to search for lepton number violating signals at the Large Hadron Collider (LHC) in the colored seesaw scenario is investigated. In this context the fields that generate neutrinoExpand
Resonance contribution of scalar color octet to tt̄ production at the LHC in the minimal four-color quark–lepton symmetry model
The scalar color octet contribution to the resonance tt-pair production at the LHC is calculated and analyzed by taking into account the one-loop effective two-gluon vertex. It is shown that thisExpand
On mass limits for scalar color octet from the LHC data on invariant mass spectra
The scalar color octet contribution to the resonance t t -pair production at the LHC is calculated and analyzed with account of the one loop effective two gluon vertex. From current LHC data on totalExpand
Heavy octets and Tevatron signals with three or four b jets
Hypothetical color-octet particles of spin 0, pair-produced at hadron colliders through their QCD coupling, may lead to final states involving three or four b jets. The scalar octets may also beExpand
Grand unification and light color-octet scalars at the LHC
We study the properties and production mechanisms of color-octet scalars at the Large Hadron Collider. We focus on the single production of both charged and neutral members of an (8,2){sub 1/2}Expand
Searching for multijet resonances at the LHC
Recently it was shown that there is a class of models in which colored vector and scalar resonances can be copiously produced at the Tevatron with decays to multijet final states, consistent with allExpand
Identifying Multi-Top Events from Gluino Decay at the LHC
We study the LHC signal of a light gluino whose cascade decay is dominated by channels involving top, and, sometimes, bottom quarks. This is a generic signature for a number of supersymmetry breakingExpand
Topological Pions
We study the collider signatures of new pions, composite particles which emerge from a TeV-scale, confining gauge theory with vector-like matter. Similar to the neutral pion in QCD, these new pionsExpand
On the Origin of Neutrino Masses
We discuss the simplest mechanisms for generating neutrino masses at tree level and one loop level. We find a significant number of new possibilities where one can generate neutrino masses at theExpand
