利用宇宙线观测数据研究1～100TeV能区质子-空气非弹性作用截面

A study of proton-air inelastic cross section at the energy region of 1-100 TeV by applying cosmic ray

    摘要
  • 摘要: 提出一种在高海拔地区通过宇宙线大气簇射过程的数值模拟,结合地面探测器阵列对簇射事例的响应,确定了直达质子事例的判选标准和判选效率.通过分析直达质子事例率,测量了1～100 TeV能区质子-空气非弹性作用截面,并结合Glauber理论计算出1～100 TeV能区质子-质子作用总截面.

     

    Abstract: We have proposed a numerical simulation of extensive air shower(EAS)of cosmic ray at high altitudes,combined with the response of detector array to ascertain the selection criteria and efficiency of directly arrived protons.We have measured the proton-air inelastic cross section at the energy region of 1-100 TeV by analyzing the probability of directly arrived protons.Additionally,the total proton-proton cross section at the energy region of 1-100 TeV has been calculated by applying Glauber theory.
