在这项工作中，我们报告的测量质子空气非弹性截面使用望远镜阵列探测器。在测量的基础上，还确定了质子-质子截面值。用望远镜阵列探测高能宇宙射线事件使我们能够研究这个基本参数，否则我们无法使用粒子加速器。本报告中使用的数据是由中间鼓荧光探测器和表面阵列探测器在五年内收集的混合事件。发现的值等于。总质子质子截面随后推断从Glauber形式主义和块，Halzen和Stanev QCD启发的适合，并被发现等于。
In this work we are reporting on the measurement of the proton-air inelastic cross sectionusing the Telescope Array detector. Based on the measurement of the, the proton-proton cross sectionvalue is also determined at. Detecting cosmic ray events at ultrahigh energies with the Telescope Array enables us to study this fundamental parameter that we are otherwise unable to access with particle accelerators. The data used in this report are the hybrid events observed by the Middle Drum fluorescence detector together with the surface array detector collected over five years. The value of theis found to be equal to. The total proton-proton cross section is subsequently inferred from Glauber formalism and the Block, Halzen and Stanev QCD inspired fit and is found to be equal to.
