abstract = {The ATLAS experiment at the Large Hadron
Collider has a broad physics programme ranging from precision
measurements to direct searches for new particles and
newinteractions, requiring ever larger and ever more accurate
datasets of simulated Monte Carlo events. Detector simulation
with Geant4 is accurate but requires significant CPU
resources. Over the past decade, ATLAS has developed and
utilized tools that replace themostCPU-intensive component
of the simulation—the calorimeter shower simulation—with
faster simulation methods. Here, AtlFast3, the next generation
of high-accuracy fast simulation in ATLAS, is introduced.
AtlFast3 combines parameterized approaches with
machine-learning techniques and is deployed to meet current
and future computing challenges, and simulation needs
of theATLAS experiment.With highly accurate performance
and significantly improved modelling of substructure within
jets,AtlFast3 can simulate large numbers of events for awide
range of physics processes.},
