引入静止标架亚喷流算法来定义SISCONE喷流的亚喷流；利用该算法，定义了红外和共线安全喷流形状可观测的N亚喷流{tau}{subN}{sup j}来区分脂肪喷流和QCD喷流，该喷流是一个高度增强的彩色单重态粒子衰变到N个部分子。利用静止标架子和{tau}{sub2}{sup j}对来自高度增强的H/W/Z玻色子的双喷流，通过m{subH}=12 0GeV的pp{educts}HW，HZ，我们发现，对于与L{约x}30Fb{sup-1}的14TeV碰撞，来自完全强子通道的信号的统计意义约为2{sigma}。
The rest frame subjet algorithm is introduced to define the subjets for the SISCone jet; with this algorithm, an infrared and collinear safe jet shape observable N-subjettiness {tau}{sub N}{sup j} is defined to discriminate the fat jet, from a highly boosted color singlet particle decaying to N partons, from the QCD jet. Using rest frame subjets and {tau}{sub 2}{sup j} on dijets from highly boosted H/W/Z bosons through pp{yields}HW,HZ with m{sub H}=120 GeV, we found that the statistical significance of the signal, from the fully hadronic channels, is about 2{sigma} for 14 TeV collisions with L{approx}30 fb{sup -1}.
