Resumen:
The determination of the primary energy of extensive air showers using the fluorescence detectiontechnique requires an estimation of the energy carried away by particles that do not deposit all their energyin the atmosphere. This estimation is typically made using Monte Carlo simulations and thus depends onthe assumed primary particle mass and on model predictions for neutrino and muon production. In thiswork we present a new method to obtain the invisible energy from events detected by the Pierre AugerObservatory. The method uses measurements of the muon number at ground level, and it allows us tosignificantly reduce the systematic uncertainties related to the mass composition and the high energyhadronic interaction models, and consequently to improve the estimation of the energy scale of the PierreAuger Observatory.
