Tevatron顶部以上的重夸克

Heavy Quarks Above the Top at the Tevatron

Anupama Atre, Marcela Carena, Tao Han, Jose Santiago

摘要:

最近的发展,在模型与扭曲的额外的维开辟了新的可能性,矢量夸克的研究在强子对撞机。这些新的矢量夸克可以与轻标准模型夸克大规模混合,而不会违反低能限制。我们执行一个独立的模型分析,以确定在寻找新的夸克的Tevatron达到。我们发现Tevatron具有很大的潜力,通过它们与价夸克的混合,通过它们的电弱单产生来观察这样的夸克。在4(8)fb-1的积分亮度下,当重夸克-标准模型夸克混合参数为一阶时,对于质量为580(630)GeV的重夸克,可以达到5σ统计显著性。

英文摘要:

Recent developments in models with warped extra dimensions have opened new possibilities for vector-like quark studies at hadron colliders. These new vector-like quarks can mix sizably with light Standard Model quarks without violating low energy constraints. We perform a model-independent analysis to determine the Tevatron reach in the search for new quarks. We find that the Tevatron has great potential to observe such quarks via their electroweak single production due to their mixing with valence quarks. With 4 (8) fb-1 integrated luminosity, one may reach a 5σstatistical significance for a heavy quark of mass 580 (630) GeV if the heavy quark-Standard Model quark mixing parameter is order one.
