Calculation of Low-Energy Atmospheric Neutrino Fluxes
Calculations of low-energy atmospheric v-fluxes (100 MeV ~ 3 GeV) have been carried out by many authors. The recent calculations include: Barr et al. (BGS) , Bugaev and Naumov (BN) , Lee and Koh (LK) , and Honda et al. (HKHM) . They agree well in the ratio (v e + v̄ e )/(v μ+ v̄ μ ) within 5%; A modest agreement of up to 20% is achieved for the v̄ e/ v e ratio. The calculations, however, do not agree in the absolute flux values by 50%. In this article, the calculation of low-energy atmospheric v—fluxes and the problem are described based on the work of HKHM.
