Time-sliced perturbation theory for large scale structures
I will introduce a new framework to account for the non-linear clustering of large-scale structures. This framework is based on the time-dependent probability distribution function considered at fixed time slices. I will first discuss the perturbative regime valid for mildly non-linear scales ranging from 10 to 100 Mpc. I will introduce techniques to account for large contributions from the IR and UV modes and compare the results with N-body data. The last part of my talk will be devoted to some aspects of the non-perturbative regime and the counts-in-cells statistics.
