Pair Production of Color-Octet Scalars at the LHC

Understand

Heavy colored scalar particles, which exist in many models of new physics, can be pair produced at the Large Hadron Collider (LHC) via gluon-gluon fusion and possibly form quarkonium-like bound states.

• If the scalars are also charged under the electroweak gauge group, these bound states can then decay into electroweak bosons.
• This yields a resonant cross section for final states such as gamma gamma that can exceed Standard Model backgrounds.
• This paper studies this process in the Manohar-Wise model of color-octet scalars (COS).
