Abstract

While the particle physics community is eagerly waiting for a positive sign for the construction of the next energy frontier collider, developments continue to advance the detector capabilities. New methods and algorithms are being implemented in order to exploit the precious collisions at a Future Higgs Factory as well as possible, informing at the same time, which detector aspects are of particular importance or in fact currently limiting. In this work, three new event analysis methods are briefly introduced and put into context of hardware development for a detector at a Future Higgs Factory. While they use data from a large Geant4-based detailed MC production of the International Large Detector at the proposed International Linear Collider at an e$^+$e$^-$ center-of-mass energy of 250 GeV, the conclusions are applicable to any Future Higgs Factory.
