  Monte Carlo simulation is an essential component of experimental particle
physics in all the phases of its life-cycle: the investigation of the physics
reach of detector concepts, the design of facilities and detectors, the
development and optimization of data reconstruction software, the data analysis
for the production of physics results. This note briefly outlines some research
topics related to Monte Carlo simulation, that are relevant to future
experimental perspectives in particle physics. The focus is on physics aspects:
conceptual progress beyond current particle transport schemes, the
incorporation of materials science knowledge relevant to novel detection
technologies, functionality to model radiation damage, the capability for
multi-scale simulation, quantitative validation and uncertainty quantification
to determine the predictive power of simulation. The R&D on simulation for
future detectors would profit from cooperation within various components of the
particle physics community, and synergy with other experimental domain sharing
similar simulation requirements.
