چکیده انگلیسی
We investigate the problem of identifying νÏ-induced reactions in large neutrino telescopes. We concentrate on events with tracks and showers where the respective energies Eμ and EX are measured separately. Then we compute analytically and numerically event distributions in two variables rl=EX/El and yâ²=EX/(Eμ+EX). We find that the yâ²-distribution is especially useful because in the νÏ-induced reactions the distribution has a minimum at yâ²=0.75 and then increases as yâ²â1. This is different in νμ-induced reactions where the yâ²-distribution decreases monotonically. The results are demonstrated with figures where one can estimate the required sensitivity of the experiments. Another attractive property is that in several ratios the neutrino flux factorizes and drops out. We hope the results of this article will be useful for searches of tau (anti)neutrinos of energies above 100 GeV to several TeV in the present and planned large volume neutrino telescopes.
