Abstract

In recent Letter by An et al. [arXiv:1203.1669] Daya Bay measurements of non-zero value for the neutrino mixing angle {\theta}_{13} with a significance of 5.2 standard deviations were reported. The value of sin^2 {\theta}_{13} was determined with a {\chi}^2 constructed with pull terms accounting for the correlation of the systematic errors. We show that a direct applying of the KamLAND parameters of mixing to Daya Bay-experiment under nonequilibrium geoneutrino spectrum of the nuclear burning process within the framework of nonzero nuclear georeactor {\chi}^2 -hypothesis will produce a high uncertainty level and, as a result, a substantial distortion of the actual value of the neutrino mixing angle {\theta}_{13}.
