Reconstruction of complex decay channels using genetic algorithm — •Áron Kripkó, Markus Moritz, and Kai-Thomas Brinkmann for the PANDA collaboration — II. Physikalisches Institut, Justus Liebig Universität Gießen, 35392 Gießen, Germany
A common problem in the topic of hadron spectroscopy is the reconstruction of complex decay channels. During the procedure cuts are applied to the properties of the reconstructed candidates along the decay tree with the aim of maximizing the significance. In case of complex decay channels, finding the optimal set of cuts is not obvious.
The application of genetic algorithm to this problem was investigated in PANDARoot. Genetic algorithm is an optimization algorithm inspired by the process of natural selection. PANDARoot is the common simulation framework for feasibility studies of the PANDA experiment.
The talk will present the reconstruction for complex decay channels with 9 final state particles for a predicted hybrid charmonium state (ηc1) with JPC=1−+ using genetic algorithm.
