FlashSim prototype: an end-to-end fast simulation using Normalizing Flow

We present a prototype of Flash-sim, a fast simulation for CMS analysis level event content (NANOAOD) based on Machine Learning. The Normalizing Flow technique is used to directly simulate reconstructed physics object information from generator level objects, skipping the full simulation and reconst...

Sumario:We present a prototype of Flash-sim, a fast simulation for CMS analysis level event content (NANOAOD) based on Machine Learning. The Normalizing Flow technique is used to directly simulate reconstructed physics object information from generator level objects, skipping the full simulation and reconstruction. The results are presented as comparison between full and flash simulation of various observables and correlations between the observables
