Abstract
I
will present the physical mechanisms that can generate primordial
nonGaussianity (PNG) during inflation. I'll then discuss the
conseqences of PNG in the CMB anisotropy pattern and the statistical
estimators used to detect/constrain it. Aspects of PNG search in
the LSS of the Universe will also be discussed. Finally, I'll mention
some nontrivial issues on the observability of PNG signatures in
CMB/LSS.
