After a description of the nature of the source, we obtain a prediction for the neutrino fluxes, based on the intense gamma ray flux first seen by CANGAROO and recently measured by H.E.S.S. experiment. We study the effect of 3 flavor oscillations in detail and consider the impact on the muon flux induced by these high energy neutrinos, potentially observable by a neutrino telescope located in the Northern hemisphere. A detector in the Mediterranean with an effective area of 1 km2 and unit detection efficiency should be able to see a signal of about 10 muons per year. Introduction The search for high energy cosmic neutrinos has a long history, tightly connected with the history of cosmic rays. The hope of a happy end is linked to neutrino telescopes presently in operation, in construction or in project. In the present work, we focus on a promising potential galac- tic source, the young supernova remnant RX J1713.7- 3946, and calculate the expected muon signal using stan- dard techniques [1, 2]. We begin by a description of this object (sect. 1), and state the predicted neutrino flux in sect. 2. In sect. 3, we evaluate precisely the impact of three flavor oscillations on the flux. The effect of the absorption of the high energy part of the flux in the Earth and of the live-time of observation is considered in sect. 4. The muon signal in neutrino telescopes is studied in sect. 5. A summary of the result is offered in sect. 6. 1 A potential neutrino source In this section, we recall the motivations of interest in supernova remnants, and a number of rece
