本文用HBT关联方法，利用Monte Carlo发生器PYTHIA 8.219产生的碰撞事例，详细研究了Higgs玻色子衰变为强子喷注（Higgs喷注）的时空结构。Higgs玻色子半径和衰变寿命的测量是由末态π介子的HBT关联导出的，上限为m和fs。该结果与CMS数据一致。
The space-time structure of the Higgs boson decaying into hadron-jets (Higgs jets) is carefully studied with the HBT correlation method usingcollision events produced by the Monte Carlo generator PYTHIA 8.219 atGeV. The measurement of the Higgs boson radius and decay lifetime are derived from the HBT correlation of the final state pions, with an upper bound offm andfs. This result is consistent with CMS data.
