209 GeV ~ 209 GeV能量下e+e碰撞中中性希格斯玻色子玻色子的最终搜索结果

Final results of the searches for neutral Higgs bosons in e+e- collisions at sqrt(s) up to 209GeV

ALEPH Collaboration

摘要:

ALEPH搜索的标准模型希格斯玻色子在LEP的最终结果,在2000年收集的数据在质心能量高达209 GeV,提出。相对于以前的出版物的变化进行了描述,并报告了一个完整的研究系统的影响。最终分析的结果证实了2000年11月在LEP对撞机关闭后不久发表的初步结果:观察到大量的事件,与$115 \Gcs$标准模型希格斯玻色子的产生一致。最后的结果的搜索中性希格斯玻色子的MSSM也报告,在$\mh$,$\mA$和$\tanb$的限制。在不可见衰变的情况下,还对$\mh$设定了限值。

英文摘要:

The final results of the ALEPH search for the Standard Model Higgs boson at LEP, with data collected in the year 2000 at centre-of-mass energies up to 209 GeV, are presented. The changes with respect to the preceding publication are described and a complete study of systematic effects is reported. The findings of this final analysis confirm the preliminary results published in November 2000 shortly after the closing down of the LEP collider: a significant excess of events is observed, consistent with the production of a $115 \Gcs$ Standard Model Higgs boson. The final results of the searches for the neutral Higgs bosons of the MSSM are also reported, in terms of limits on $\mh$, $\mA$ and $\tanb$. Limits are also set on $\mh$ in the case of invisible decays.
