“…Main purpose of the development of the Time Sequential Procedure is the application to KM3 physics. However, another ones are the application to both the energy spectrum of muons underground or underwater and to the range energy fluctuation problem under different photonuclear interactions ( [28], [35], [38], [39], [40], [41]) because the muonnucleus inelastic scattering (photonuclear interaction) is of prime interest in another aspect.…”

“…Above approximately E = 10 10 GeV, tau charged current interactions are more important than tau decays for eliminating taus from the flux, however, in this regime, electromagnetic energy loss dominates the tau interactions. Weak neutral current contributions to the tau energy loss are quite small [69]. We include weak interaction effects in the Monte Carlo program for tau propagation.…”

We consider propagation of high-energy earth-skimming taus produced in interactions of astrophysical tau neutrinos. For astrophysical tau neutrinos, we take generic power-law flux, E −2 and the cosmogenic flux initiated by the protons. We calculate tau energy loss in several approaches, such as dipole models and the phenomenological approach in which parametrization of the F 2 is used. We evaluate the tau neutrino charged-current cross section using the same approaches for consistency. We find that uncertainty in the neutrino cross section and in the tau energy loss partially compensate giving very small theoretical uncertainty in the emerging tau flux for distances ranging from 2 to 100 km and for the energy range between 10 6 and 10 11 GeV, focusing on energies above 10 8 GeV. When we consider uncertainties in the neutrino cross section, inelasticity in neutrino interactions and the tau energy loss, which are not correlated, i.e. they are not all calculated in the same approach, theoretical uncertainty ranges from about 30% and 60% at 10 8 GeV to about factors of 3.3 and 3.8 at 10 11 GeV for the E −2 flux and the cosmogenic flux, respectively, for the distance of 10 km rock. The spread in predictions significantly increases for much larger distances, e.g., ∼1; 000 km. Most of the uncertainty comes from the treatment of photonuclear interactions of the tau in transit through large distances. We also consider Monte Carlo calculation of the tau propagation and we find that the result for the emerging tau flux is in agreement with the result obtained using analytic approach. Our results are relevant to several experiments that are looking for skimming astrophysical taus, such as the Pierre Auger Observatory, HAWC and Ashra. We evaluate the aperture for the Auger and discuss briefly application to the other two experiments.

“…Finally, we remark that the tau weak interaction effects are small compared to electromagnetic energy loss except at the very highest energies. Specifically, tau charged current interactions only become important at E > 10 10 GeV, but overshadowed by electromagnetic energy loss in this regime, and tau neutral current are quite small [57]. Figure 3.9 shows the difference between including and not including the charged current effects in evaluating the survival probability using BDHM parametrization.…”
