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

## by Dr. Vincent Desjacques (University of Geneva)

 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.
