Description
Experiments in the upcoming high-luminosity runs at the LHC face the
challenges of very large pile-up. Primary techniques to deal with this are
based on vertexing by trackers. Outside the detector tracking acceptances,
however, lie regions of much interest for a great many aspects of the
LHC physics program. Treatments of pile-up in these regions rely more
strongly on Monte Carlo simulations. Here, on the other hand, one is also
approaching parts of the phase space in which the tuning of the Monte
Carlo event generators becomes subject to increasingly large uncertainties.
In this work we explore complementary approaches to pile-up corrections,
with a view to developing data-driven techniques which treat pile-up and
do not spoil the physics of the signal process. We present numerical
illustrations of these approaches for a variety of processes, including
Drell-Yan vector boson production, Drell-Yan plus jets, and associated
underlying events.
