在D0上具有单光子和丢失能量末态的物理

Physics with Single Photons plus Missing Energy Final States at D0

Edgar Carrera

摘要:

单光子的末态特征和缺失的横向能量为寻找新物理学提供了独特而强大的优势。本文介绍了在Tevatron对撞机上首次观测到的Zgamma到nunu_bargamma过程,其标准差显著性为5.1,以及迄今为止对异常三线性ZZgamma和Zgammagamma耦合的一些最强限制。此外,我们提出了最新的D0结果的直接生产的卡鲁扎克莱因引力子与单光子的搜索。

英文摘要:

Final state signatures of a single photon and missing transverse energy offer unique and powerful advantages in the search for new physics. This document presents the first observation of the Zgamma to nunu_bargamma process at the Tevatron Collider at 5.1 standard deviations significance, as well as some of the strongest limits on anomalous trilinear ZZgamma and Zgammagamma couplings to date. Additionally, we present the latest D0 results on a search for direct production of Kaluza Klein gravitons in association with single photons.
