Title: New exact results in multiparticle correlation techniques


Multiparticle correlation techniques are today the primary experimental tool used to study the anisotropic flow phenomenon in heavy-ion collisions. The publications on anisotropic flow measurements at Large Hadron Collider are, together with publications on the discovery of the Higgs boson, the most cited recent publications in the field of high energy physics, making it one of the “hottest” research topics in the field. Although multiparticle correlations are widely used in anisotropic flow measurements, mathematical and statistical properties of them still have to be fully understood, and the sources of remaining systematic biases have to be identified and removed. In this talk I will present a new generic framework which enables exact and fast evaluation of all multiparticle azimuthal correlations [1], and discuss the progress which has been made recently in the understanding of their fundamental mathematical and statistical properties [2].
