在CERN SPS（NA65）的DsTau实验中，提出了一种独立而直接的方法来测量高能质子相互作用后的τ中微子产生。由于τ中微子的主要来源是质子与核相互作用中产生的D s介子的衰变，因此该项目的目标是测量该反应的微分截面。实验方法是基于使用高分辨率乳胶探测器的有效登记的事件与短寿命的粒子衰变。在这里，我们提出的动机的研究，实验技术的细节，并在测试运行过程中收集的数据分析的第一个结果，这证明了在未来的过程中的全面研究的可行性。
In the DsTau experiment at the CERN SPS (NA65), an independent and direct way to measure tau neutrino production following high energy proton interactions was proposed. As the main source of tau neutrinos is a decay of D s mesons, produced in proton-nucleus interactions, the project aims at measuring a differential cross section of this reaction. The experimental method is based on a use of high resolution emulsion detectors for effective registration of events with short lived particle decays. Here we present the motivation of the study, details of the experimental technique, and the first results of the analysis of the data collected during test runs, which prove feasibility of the full scale study of the process in future.
