Resumo

We perform a simulation on the DUNE experiment to probe the capability of future neutrino longbaseline experiments to constrain the parameter space of high-energy models by using the correlation between the atmospheric and reactor mixing angles. As an example, we analyze the tetrahedral flavor symmetry model, which predicts a strong relation between the nonzero value of theta(13) and a deviation of theta(23) from maximality. We show that in this case, the model can realistically be excluded by more than 3 sigma for most of the parameter space. We also study the octant degeneracy at DUNE and its impact on the sensitivity of such models. (AU)
