论文摘要
在本说明中，$ \ mathrm {zhh} $生产在$ \ mathrm {e}^{+}^{+} \ mathrm {e}^{ - }^{ - } $ collisions以紧凑型线性碰撞器的3 tev阶段中研究了$ \ mathrm {e}^{+}^{+Mathrm {e}^{ - }。在这个阶段，此Higgs Boson对生产模式在$ \ Mathrm {W}^{+} \ Mathrm {w}^{ - } $融合生产横截面$ \ Mathrm {e}这些事件的特征是六架喷气式的拓扑，其中两个喷气式的三个配对组合的质量与源自两个$ \ mathrm {h} $和一个$ \ mathrm {z} $ bosons兼容。事件选择集中在主要的$ \ mathrm {h} $玻色子衰减到两个b Quarks上，这需要有多个B-jets。该研究基于使用Clicdet模型的完整模拟，包括$γγ\ Rightarrow \ Mathrm {Hadrons} $的光束诱导的背景。给出了总$ \ mathrm {zhh} $横截面的测量结果。
In this note, $\mathrm{ZHH}$ production in the all-hadronic final state is studied in $\mathrm{e}^{+}\mathrm{e}^{-}$ collisions at the Compact Linear Collider at the 3 TeV stage. At this stage this Higgs boson pair production mode is sub-leading to the $\mathrm{W}^{+}\mathrm{W}^{-}$ fusion production cross-section of $\mathrm{e}^{+}\mathrm{e}^{-}\rightarrow\mathrm{HH}νν$. The events are characterised by a topology of six jets, where the masses of the three pair-wise combinations of two jets are compatible with originating from two $\mathrm{H}$ and one $\mathrm{Z}$ bosons. The event selection concentrates on the dominant $\mathrm{H}$ boson decays into two b-quarks by requiring a presence of multiple b-jets. The study is based on full simulation using the CLICdet model, including beam-induced backgrounds from $γγ\rightarrow\mathrm{hadrons}$. Results on the measurement of the total $\mathrm{ZHH}$ cross section are given.
