在D0上寻找带电的希格斯玻色子

Search for charged Higgs Bosons at D0

Y. Peters

摘要:

在超对称和一般的双希格斯玻色子模型(2 HDM)中,带电的希格斯玻色子玻色子$H^+-表现出独特的唯象特征。我们报告了对带电希格斯玻色子玻色子的搜索,使用费米实验室Tevatron ppbar对撞机上D 0探测器收集的0.9 fb^-1数据,质心能量为\sqrt{s} =1.96 TeV。没有证据表明带电的希格斯玻色子被发现,我们设置限制其生产截面或分支分数。

英文摘要:

In both Supersymmetry and in generic Two Higgs Doublet models (2HDM), the charged Higgs boson $H^+- exhibits a unique phenomenological signature. We report on a search for charged Higgs bosons, performed using 0.9 fb^-1 of data collected with the D0 detector at the Fermilab Tevatron ppbar collider with a center-of-mass energy of \sqrt{s}=1.96 TeV. No evidence for a charged Higgs boson is found and we set limits on its production cross section or the branching fraction.
