高能强子相互作用对大气中微子通量预测的影响

Impact of high-energy hadron interactions on the atmospheric neutrino flux predictions

A. A. Kochanov, T. S. Sinegovskaya, S. I. Sinegovsky

摘要:

研究了强子相互作用特征对高能大气中微子谱的影响。利用已知的高能强子模型SIBYLL 2.1、QGSJET-II、Kimel和Mokhov对测量数据中的初级宇宙线谱进行了参数化的一维计算。结果进行了比较与Frejus数据和AMANDA-II测量以及与其他计算。SIBYLL和QGSJET-II获得的中微子通量的巨大差异(在1 TeV时高达1.8倍)似乎是相当出乎意料的,请记住在同一能量区域的强子和μ子通量计算。

英文摘要:

We study the influence of hadron interaction features on the high-energy atmospheric neutrino spectrum. The 1D calculation is performed with use of the known high-energy hadronic models, SIBYLL 2.1, QGSJET-II, Kimel and Mokhov, for the parameterizations of primary cosmic ray spectra issued from the measurement data. The results are compared with the Frejus data and AMANDA-II measurements as well as with other calculations. Sizable difference of the neutrino fluxes (up to the factor of 1.8 at 1 TeV) that are obtained with the SIBYLL and QGSJET-II appears to be rather unexpected keeping in mind the hadron and muon flux calculations in the same energy region.
