LHC的大喷流多重性和新物理

Large Jet Multiplicities and New Physics at the LHC

Joseph Bramante, Jason Kumar, Brooks Thomas

摘要:

新物理学的一大类场景涉及额外的强相互作用场,通常预测强子对撞机的签名仅由大量喷流和大量缺失的横向能量组成。在这项工作中,我们调查的前景,发现在这种情况下使用的搜索策略,其中射流的多样性和失踪的横向能量作为区分信号与背景的主要标准。我们研究发现达到这个策略提供了一个例子理论(一个简化的超对称模型,其低能谱由一个胶子,一个光停止,和一个轻中性子),并证明它经常超过通过其他替代策略获得的范围。

英文摘要:

A broad class of scenarios for new physics involving additional strongly-interacting fields generically predicts signatures at hadron colliders which consist solely of large numbers of jets and substantial missing transverse energy. In this work, we investigate the prospects for discovery in such scenarios using a search strategy in which jet multiplicity and missing transverse energy are employed as the primary criteria for distinguishing signal from background. We examine the discovery reach this strategy affords in an example theory (a simplified supersymmetric model whose low-energy spectrum consists of a gluino, a light stop, and a light neutralino) and demonstrate that it frequently exceeds the reach obtained via other, alternative strategies.
