利用大气μ介子通量对强子相互作用模型中预测的带电粒子能谱的限制

Constraints on the energy spectra of charged particles predicted in some model interactions of hadrons with help of the atmospheric muon flux

L. G. Dedenko, G. F. Fedorova, T. M. Roganova

摘要:

结果表明,在能量为10^4 GeV时,用EPOS LHC和EPOS 1.99模型计算的μ子通量强度比经典实验L3+Cosmic、MACRO和LVD的大气μ子谱数据高1.9倍,而用QGSJET II-03模型计算的μ子通量强度比这些数据低1.8倍。结果表明,这些模型高估了强子相互作用中能量最高的次级粒子的产生(QGSJET II-03模型低估了次级粒子的产生),高估系数约为1.5。LHCf和TOTEM加速器实验也表明,在次级粒子的最高能量下,这些模型的预测与这种类型的不一致。

英文摘要:

It has been shown that muon flux intensities calculated in terms of the EPOS LHC and EPOS 1.99 models at the energy of 10^4 GeV exceed the data of the classical experiments L3+Cosmic, MACRO and LVD on the spectra of atmospheric muons by a factor of 1.9 and below these data at the same energy by a factor of 1.8 in case of the QGSJET II-03 model. It has been concluded that these tested models overestimate (underestimate in case of QGSJET II-03 model) the production of secondary particles with the highest energies in interactions of hadrons by a factor of ~1.5. The LHCf and TOTEM accelerator experiments show also this type of disagreements with these model predictions at highest energies of secondary particles.
