CERN大型强子对撞机上的色六重标量

Color Sextet Scalars at the CERN Large Hadron Collider

Chuan-Ren Chen, William Klemm, Vikram Rentala, Kai Wang

摘要:

采用唯象的方法,我们研究了在大型强子对撞机上的色六重标量。我们着重研究了色六重态对Φ_6 \bar Φ_{6}通过gg熔合和q \bar{q}湮灭的QCD产生.它与\bar{ψ^c}夸克的独特耦合使色六重标量衰变为同号双夸克态,如Φ_6 \to tt/tt^*。我们提出了一种新的重建方法,在多喷注加同号双轻子中,利用缺失的横向能量样本,从六重标量对产生中寻找壳层上的tt \bar{t} \bar{t}末态.由于量子色动力学的大规模生产,对于100 fb^-1积分亮度,搜索范围可达1 TeV。

英文摘要:

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_6\barΦ_{6} through gg fusion and q\bar{q} annihilation. Its unique coupling to \bar{ψ^c}ψallows the color sextet scalar to decay into same-sign diquark states, such as Φ_6\to tt/tt^*. We propose a new reconstruction in the multijet plus same sign dilepton with missing transverse energy samples to search for on-shell tt\bar{t}\bar{t} 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.
