abstract = {Fast simulation of the energy depositions in high-granular
detectors is needed for future collider experiments with
ever increasing luminosities. Generative machine learning
(ML) models have been shown to speed up and augment the
traditional simulation chain. Many previous efforts were
limited to models relying on fixed regular grid-like
geometries leading to artifacts when applied to highly
granular calorimeters with realistic cell layouts. We
present CaloClouds III, a novel point cloud diffusion model
that allows for high-speed generation of realistic
electromagnetic showers due to the distillation into a
consistency model. The model is conditioned on incident
energy and impact angles and implemented into a realistic
DD4hep based simulation model of the ILD detector concept
for a future Higgs factory. This is done with the
DDFastShowerML library which has been developed to allow for
easy integration of generative fast simulation models into
any DD4hep based detector model. With this it is possible to
benchmark the performance of a generative ML model using
fully reconstructed physics events by comparing them against
the same events simulated with Geant4, thereby ultimately
judging the fitness of the model for application in an
experiment’s Monte Carlo.},
