通过LHC的前向质子探测器能“看到”看不见的物体吗?

Can invisible objects be `seen' via forward proton detectors at the LHC?

V. A. Khoze, A. D. Martin, M. G. Ryskin

摘要:

我们讨论了识别不可见的对象(例如暗物质)通过中央独占过程中丢失的质量的可能性,也就是说,在事件中,只有向前质子在大型强子对撞机检测。我们表明,信号必须有一个截面大于0.25 FB,以便它可以被检测到。我们估计软质子离解所造成的巨大背景,并评估了充分抑制这些事件所需的探测器“否决”系统的要求。此外,我们讨论了相关的过程,导致可能的识别粒子从所谓的“压缩质量超越标准模型(BSM)”的情况。在这种情况下,背景并不那么严重。

英文摘要:

We discuss the possibility of identifying invisible objects (e.g. dark matter) via missing mass in Central Exclusive Processes; that is, in events where only forward protons are detected at the LHC. We show that the signal must have a cross section greater than 0.25 fb in order that it can be detected. We estimate the huge background caused by soft proton dissociation and evaluate the requirements of the detector `veto' system needed to sufficiently suppress these events. In addition, we discuss the related process leading to the possible identification of the particles from the so-called `compressed-mass Beyond the Standard Model (BSM)' scenarios. In this case the background is not so severe.
