It is well known that the standard formula for neutrino oscillation probability is  approximate because of a number of assumptions in its derivation, such as the plane wave approximation. The wave-packet treatment provides a self-consistent way to describe the phenomenon of interference of coherent mass neutrino eigenstates and predicts a number of potentially observable effects like loss of coherence and a specific modification of the neutrino energy spectrum. Currently theoretical estimates of these effects range by orders of magnitude and a lack of experimental investigations make them very desirable. The Daya Bay Experiment has collected the largest statistics of reactor antineutrino interactions. Its eight antineutrino detectors having a good energy resolution of 7.5%/sqrt(E/MeV) and are placed at various baselines (~500m for near sites and ~1600 m for the far sites) from the three reactor plants, providing a unique platform to test possible deviations from the conventional neutrino oscillation formula. In this talk we discuss the status of the experimental study of the decoherence effect in the Daya Bay experiment.
