Distinguishing Color-Octet and Color-Singlet Resonances at the Large Hadron Collider

Understand

Di-jet resonance searches are simple, yet powerful and model-independent, probes for discovering new particles at hadron colliders.

• Once such a resonance has been discovered it is important to determine the mass, spin, couplings, chiral behavior and color properties to determine the underlying theoretical structure.
• We propose a new variable which, in the absence of decays of the resonance into new non-standard states, distinguishes between color-octet and color-singlet resonances.
• To keep our study widely applicable we study phenomenological models of color-octet and color-singlet resonances in flavor universal as well as flavor non-universal scenarios.
