The Belle II software is completely new and is used for everything from triggering data, generation of Monte Carlo simulation, tracking, clustering, and for high-level analysis. One important feature is the matching between the combinations of reconstructed objects which form particle candidates and the underlying simulated particles from the event generators. This is used to study detector effects, analysis backgrounds, and efficiencies. This document describes the algorithm that is used by Belle II. 000002747 6531_ $$amc-matching 000002747 6531_ $$asimulated 000002747 6531_ $$asoftware 000002747 6531_ $$acomposite 000002747 6531_ $$ainclusive 000002747 6531_ $$adecaystring grammar 000002747 700__ $$aSam Cunliffe 000002747 700__ $$aFrank Meier 000002747 700__ $$aAnze Zupanc 000002747 8560_ $$fyosato@post.kek.jp 000002747 8564_ $$uhttps://docs.belle2.org/record/2747/files/BELLE2-TALK-CONF-2021-134.pdf
