On the non-Gaussian bias derived from the local bias model

Description
I will discuss the effect of local primordial non-Gaussianity on the 2-point function 
of biased tracers within the excursion set peak model. I will show that the non-Gaussian
bias of these discrete tracers can be straightforwardly computed from an effective local bias 
expansion and will explain why the standard local bias model has failed so far at predicting
the correct non-Gaussian bias amplitude.
