Abstract: In the framework of open quantum systems, we analyze data from KamLAND by using a model that considers neutrino oscillation in a three-family approximation with the inclusion of the decoherence effect. Using chi(2) test, we find new limits for the decoherence parameter, which we call gamma, considering the most recent data by KamLAND. Assuming an energy dependence of the type gamma=gamma(0) (E/E-0)(n), at a 95% C.L., the limits found are 3.7 x 10(-24) GeV for n=-1, 6.8 x 10(-22) GeV for n=0, and 1.5 x 10(-19) GeV for n=1 on the energy dependence.
