Taking a phenomenological approach, we study a color sextet scalar at the LHC. We focus on the QCD production of a color sextet pair Φ 6Φ̄6 through gg fusion and qq̄ annihilation. Its unique coupling to ψ̄cψ 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+ ± ±+E T+Nj, N6) to search for on-shell ttt̄t̄ 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 100fb-1 integrated luminosity.
