Theo will be exploring the performance of the Effective Field Theory of Large Scale Structure at the one loop level for the four point function. In contrast to previous studies he will be working with a realisation based perturbation theory calculation that can be directly compared to the outcome of N-body simulations circumventing cosmic variance and convergence of covariance matrices. Further onward he will be moving the higher loops for the two point function and higher order correlators at the two-loop level.

Theo将在四点函数的单圈水平上探索大尺度结构的有效场理论的性能。与以前的研究相比，他将使用基于实现的微扰理论计算，该计算可以直接与N体模拟的结果进行比较，从而规避宇宙方差和协方差矩阵的收敛。进一步，他将移动两点函数的更高循环和两循环级别的更高阶的迭代器。
