Abstract
We consider the CMB bispectrum signal induced by structure formation through the correlation between the Integrated Sachs-Wolfe and the weak lensing effect. We investigate how the bispectrum knowledge can improve our knowledge of the most important cosmological parameters, focusing on the dark energy ones. Preliminary results suggest a consistent improvement on the estimation of dark energy abundance and on dynamical properties of the equation of state.
