摘　　要：在积分亮度为300 fb^(-1)、√s=14 TeV的条件下,通过蒙特卡罗法模拟大型强子对撞机上的对撞事例,分析双希格斯二重态模型预言的重中性希格斯玻色子H的产生和衰变过程:pp→H→hh→τ^(+)τ^(-)τ^(+)τ^(-),发现最终末态为l^(±)vvl^(±)vvτ_(j)τ_(j)(l=e,μ)信号,说明满足过往实验及理论的要求下,在大型强子对撞机上发现4τ信号的可能性很大。This paper simulates collision events on the large hadron collider(LHC)by the Monte Carlo method under the conditions of integrated luminosity of 300 fb^(-1)and√s=14 TeV.Further,it analyzes the production and decay process(pp→H→hh→τ^(+)τ^(-)τ^(+)τ^(-))of the heavy-neutral Higgs boson(H)predicted by the two-Higgs-doublet model and finds that the final state is l^(±)vvl^(±)vvτ_(j)τ_(j)(l=e,μ)signal.This illustrates the high probability of discovering a 4τsignal at the LHC when the requirements of past experiments and theories are met.
