Color Sextet Scalars at the CERN Large Hadron Collider

Abstract [en]

Taking a phenomenological approach, we study a color sextet scalar at the LHC. We focus on the QCD production of a color sextet pair Φ6Φ̅ 6 through gg fusion and qq̅ annihilation. Its unique coupling to ψ̅ cψ allows the color sextet scalar to decay into same-sign diquark states, such as Φ6→tt/tt*. We propose a new reconstruction in the multijet plus same-sign dilepton with missing transverse energy samples (bb+ℓ±±+E̸T+Nj, N≥6) to search for on-shell ttt̅ t̅ final states from sextet scalar pair production. Thanks to the large QCD production, the search covers the sextet mass range up to 1 TeV for 100  fb-1 integrated luminosity.
