Short-lived particles that have very small production probability or small branching ratio are of particular interest in the future heavy-ion experiment CBM at FAIR. Such particles can be reconstructed and investigated only through their decay products. The KF Particle Finder package was developed for reconstruction of short-lived particles in the CBM experiment. Currently its reconstruction scheme contains more than 100 decay channels.
Large multiplicities of charged particles produced in heavy ion collisions lead to combinatorial background in the reconstructed spectra of short-lived particles. KF Particle Finder provides the machinery to correctly take into account the background and obtain the signal spectra. It allows to collect efficiency plots, extract efficiency corrected spectra and perform their multi-differential analysis. The rich functionality of KF Particle Finder makes it a universal platform for physics analysis.
