  The propagation of neutrinos in long baselines experiments may be influenced
by dissipation effects. Using Lindblad Master Equation we evolve neutrinos
taking into account these dissipative effects. The MSW and the dissipative
effects may change the probabilities behavior. In this work, we show and
explain how the behavior of the probabilities can change due to the decoherence
and relaxation effects acting individually with the MSW effect. A new exotic
peak appears in this case and we show the difference between the decoherence
and relaxation effects in the appearance of this peak. We also adapt the usual
approximate expression for survival and appearance probabilities with all
possible decoherence effects. We suppose the baseline of DUNE and show how each
decoherence parameters change the probabilities analyzing the possible
modification using numeric and analytic approach.
