Minimal matter at the large hadron collider Original Research Article

We classify all possible new image multiplets that can couple to pairs of SM particles. Assuming that production of such new particles is dominated by their gauge interactions we study their signals at LHC, finding the following five main classes: (i) lepto-quark image signals; (ii) di-lepton 4ℓ signals; (iii) di-quarks 4j signals, (iv) heavy-lepton image signals and (v) heavy quarks image signals, where V denotes heavy SM vectors (with W being associated to exotic fermions). In each case we outline the most promising final states, the SM backgrounds and propose the needed searches.
