Measurement of the differential charm production cross-section of protons on a thick target using pixel detectors (CharmDXSPix)

粒子物理学的标准模型很好地描述了最小的粒子和相互作用的力。实验室的所有测量结果都证实了这一理论的正确性。然而，有迹象表明，特别是通过对宇宙的观察，这一理论一定有延伸，例如，存在进一步的，尚未发现的粒子或相互作用。例如，欧洲核子研究中心（CERN）的大型强子对撞机（Large Hadron Collider）目前正在测试这些扩展，但尚未发现。或者，如果收集到足够大的数据集，即使在较低的碰撞能量下，也可以发现非常弱的新力。未来的束流转储实验可能是解决问题的关键。在这些实验中，主要产生粲强子，这些粲强子可以衰变成新的粒子。拟议的项目旨在测量产生迷人强子的概率。新颖之处在于两种完全不同的探测器被一起使用：乳剂和像素探测器。一个主要的挑战是这两个组件的相互作用。

The Standard Model of particle physics describes the smallest particles and the forces that act upon each other excellently. All measurements in the laboratory confirm the validity of this theory. However, there are indications, especially through observations of the Universe, that there must be extensions of this theory, e.g. the existence of further, not yet discovered particles or interactions. These extensions are being tested today, for example, at the Large Hadron Collider at CERN, but have not yet been found. Alternatively, very weak, novel forces can be found if sufficiently large data sets are collected – even at lower collision energies. Future beam-dump experiments may hold the key. In such experiments, mainly charm hadrons are produced, which can decay into novel particles. The proposed project aims to measure the probability of the production of charm hadrons. The novelty is that two completely different detectors are used together: emulsions and pixel detectors. A major challenge is the interaction of these two components.
