Possible exotic stringy signatures at the LHC
  In this paper I discuss some string inspired exotic colored matter particles that could be produced at the LHC, as well as the experimental signature for the observation of such states. Their most easily identifiable signature of this scenario is that many of these exotic particles would decay into standard model particles only via higher dimension operators in the effective field theory at a TeV scale. Some of these particles would only have three body decays into standard model particles.
