Abstract: In this work, we analyze quantum decoherence in neutrino oscillations considering the open quantum system framework and oscillations through matter for three-neutrino families. Taking the Deep Under-ground Neutrino Experiment as a case study, we performed sensitivity analyses for two neutrino flux configurations, finding sensitivity limits for the decoherence parameters. We also offer a physical interpretation for a new peak which arises at the nu(e) appearance probability with decoherence. The sensitivity limits found for the decoherence parameters are Gamma(21) <= 1.2 x 10(-23) GeV and Gamma(32) <= 7.7 x 10(-15) GeV at 90% C.L
