Understand
Existing widely-used pileup removal approaches correct the momenta of individual jets.
- In this article we introduce an event-level, particle-based pileup correction procedure, SoftKiller.
- It removes the softest particles in an event, up to a transverse momentum threshold that is determined dynamically on an event-by-event basis.
- In simulations, this simple procedure appears to be reasonably robust and brings superior jet resolution performance compared to existing jet-based approaches.
