用ATLAS探测器在有喷流和缺少横向动量的事件中寻找暗物质候选者和大额外维度

Search for dark matter candidates and large extra dimensions in events with a jet and missing transverse momentum with the ATLAS detector

The ATLAS Collaboration

摘要:

利用大型强子对撞机ATLAS实验在sqrt(s)=7 TeV的质子-质子碰撞数据,对高能喷流和大的横向动量缺失事件中的新现象进行了研究.四个运动学区域探索使用对应于4.7逆毫微微巴恩的积分亮度的数据集。没有观察到超出标准模型过程预期的事件,并且对大的额外维度和暗物质粒子的成对产生设定了限制。

英文摘要:

A search for new phenomena in events with a high-energy jet and large missing transverse momentum is performed using data from proton-proton collisions at sqrt(s)=7 TeV with the ATLAS experiment at the Large Hadron Collider. Four kinematic regions are explored using a dataset corresponding to an integrated luminosity of 4.7 inverse femtobarn. No excess of events beyond expectations from Standard Model processes is observed, and limits are set on large extra dimensions and the pair production of dark matter particles.
