The IR-resummed Effective Field Theory of Large Scale Structures

Senatore, Leonardo, Zaldarriaga, Matias

Understand

We present a new method to resum the effect of large scale motions in the Effective Field Theory of Large Scale Structures.

Because the linear power spectrum in $\Lambda$CDM is not scale free the effects of the large scale flows are enhanced.
Although previous EFT calculations of the equal-time density power spectrum at one and two loops showed a remarkable agreement with numerical results, they also showed a 2% residual which appeared related to the BAO oscillations.
We show that this was indeed the case, explain the physical origin and show how a Lagrangian based calculation removes this differences.
