摘要:

我们发现,CDF合作最近报告的结果显示,在与W-玻色子产生的喷流对的不变质量分布过剩,可以解释一个简单的扩展标准模型(SM)与一个额外的准惰性希格斯偶极子。另外两个中性希格斯态H^0和A^0的质量约为150 GeV,并衰变为一对喷流。W^ \pm H^0/A^0对是由较重的荷电希格斯玻色子H^ \pm衰变产生的。根据中性和带电希格斯玻色子的精确质量,该模型被证明是一致的约束,从电弱精密测试和从味物理广泛的标准模型-如希格斯质量从100 GeV到几百GeV。其他可能的信号,这个模型在Tevatron和LHC进行了讨论。

英文摘要:

We show that, the result recently reported by the CDF collaboration showing an excess in the invariant mass distribution of jet pairs produced in association with a W-boson can be explained by a simple extension of the Standard Model (SM) with an additional quasi-inert Higgs doublet. The two additional neutral Higgs states H^0 and A^0 have a mass of about 150 GeV and decay into a pair of jets. W^\pm H^0/A^0 pairs are produced from the decay of the heavier charged Higgs boson H^\pm. Depending on the precise masses of the neutral and charged Higgs bosons, the model is shown to be in agreement with constraints from electroweak precision tests and from flavor physics for a broad range of the Standard Model-like Higgs mass from 100 GeV to several hundreds of GeV. Other possible signals of this model at the Tevatron and the LHC are discussed.
