Tevatron上延时光子+ MET末态中h^0 -> χ_1^0 χ_1^0产生的规范介导超对称性的研究前景

Prospects of Searches for Gauge Mediated Supersymmetry with h^0 -> χ_1^0 χ_1^0 production in the Time-Delayed Photon + MET Final State at the Tevatron

John D. Mason, David Toback

摘要:

我们提出了一个在费米实验室Tevatron的规范介导模型中寻找最轻的超对称希格斯玻色子直接产生和衰变为两个中性伴子的方法。我们专注于最终状态,每个中性伴子衰变为光子和轻引力伴子,寿命为O(ns)。在探测器中,这将显示为具有时间延迟签名和缺失E_T的光子。我们估计,使用光子定时系统在CDF,和完整的10/FB数据样本,灵敏度可以在参数空间的某些区域的三个因素直接生产的希格斯粒子。

英文摘要:

We propose a search for direct production and decay of the lightest supersymmetric Higgs boson to two neutralinos in gauge mediated models at the Fermilab Tevatron. We focus on the final state where each neutralino decays to photon and light gravitino with a lifetime of order O(ns). In the detector this will show up as a photon with a time-delayed signature and missing E_T. We estimate that using the photon timing system at CDF, and the full 10/fb data sample, that the sensitivity can be within a factor of three in some regions of parameter space for direct production of the Higgs.
