Description
In the standard cosmological paradigm, the initial condition follows Gaussian statistics. At later times, gravitational evolution induces nonlinearities in the large-scale structure, and information that had been fully captured by the two-point statistics gets spread into higher-order statistics. In this talk, I will present our recent progress on the N-point Correlation Function (NPCF) for N up to 6, including an analytic formalism for the Gaussian covariance matrix and the first detection of the 4PCF due to nonlinear structure formation. Finally, I will discuss our recent analysis of parity-odd modes of the 4PCF using the data from the Baryon Oscillation Spectroscopic Survey (BOSS).
