Searching for multijet resonances at the LHC

Abstract

Recently it was shown that there is a class of models in which colored vector\nand scalar resonances can be copiously produced at the Tevatron with decays to\nmultijet final states, consistent with all experimental constraints and having\nstrong discovery potential. We investigate the collider phenomenology of TeV\nscale colored resonances at the LHC and demonstrate a strong discovery\npotential for the scalars with early data as well as the vectors with\nadditional statistics. We argue that the signal can be self-calibrating and\nusing this fact we propose a search strategy which we show to be robust to\nsystematic errors typically expected from Monte Carlo background estimates. We\nmodel the resonances with a phenomenological Lagrangian that describes them as\nbound states of colored vectorlike fermions due to new confining gauge\ninteractions. However, the phenomenological Lagrangian treatment is quite\ngeneral and can represent other scenarios of microscopic physics as well.\n
