DISCOVERY brings together strong groups in various physics fields to study the morphology of Cosmic Microwave Background (CMB) and Heavy Ion Collisions (HIC). Through unique access to data from powerful experiments like the Large Hadron Collider (LHC) and the Planck satellite mission, the project aims to explore common features and perspectives in these seemingly distinct areas. Topics covered include the theory of inflation, dark matter, isocurvature perturbations, and the impact of heavy ion collisions on CMB phenomena. The presentation discusses statistical ensembles, elliptic flow, di-jet and multi-jet events, and simulations to analyze event morphology in heavy ion and particle physics. The goal is to develop methods for analyzing collective phenomena and point sources, with plans for realistic event simulations and further analysis of ALICE events from LHC Pb+Pb collisions.
