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±vvτjτj(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.
Abstract
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±vvτjτj(l=e,µ)signal.This illustrates the high probability of discovering a 4τ signal at the LHC when the requirements of past experiments and theories are met.
