RESUMO:

One of the Deep Underground Neutrino Experiment (DUNE) potentials is the detection of neutrinos from supernova (SN). Most of these neutrinos emerge from inner regions of the SN, crossing a turbulent and catastrophic environment almost intactly, carrying, thus, with them pure and valuable information to the study of SN as well as to the study of neutrino physics. Neutrino is a massive particle and its mass is responsible for a delay in the time of arrival on Earth, if compared to photons. This delay and the transition processes that occur in the resonant layers of the star are extremely important for obtaining a limit for the effective mass of SN electronic neutrinos. The physical mechanisms that lead to the core collapse and, consequently, to the SN explosion are not yet fully understood, what makes the results obtained from simulations strongly constrained to the model used. In this work, we conduct an analysis for DUNE of how the Garching model of core collapse Supernovae can be used to obtain an upper limit for the effective mass of the electronic neutrino. For this, we use a specific model with 13.8 solar masses for the progenitor star of SN at a distance of 10 kpc. The same method can be applied to other models. In order to calculate the number of events in the detector, we consider a mass of 40 kton of liquid argon, similar to that of the DUNE far detector.
