A new generation of experiments is being developed, where the challenge of separating rare signal processes from background at high intensities requires a change of trigger paradigm. At the future PANDA experiment at FAIR, hardware triggers will be abandoned and instead a purely software-based system will be used. This requires novel reconstruction methods with the ability to process data from many events simultaneously. A 4D tracking algorithm based on the cellular automaton has been developed which will utilize the timing information from detector signals. Simulation studies have been performed to test its performance on the foreseen free-streaming data from the PANDA detector. For this purpose, a quality assurance procedure for tracking on free-streaming data was implemented in the PANDA software. The studies show that at higher interaction rates, 4D tracking performs better than the 3D algorithm in terms of efficiency, 84% compared to 77%. The fake track suppression is also greatly improved, compared to the 3D tracking with roughly a 50% decrease in the ghost rate.

The PANDA experiment is one of the pillars of the new Facility for Antiproton and Ion Research, currently under construction in Darmstadt, Germany. PANDA will be a fixed-target experiment which will study non-perturbative strong interaction phenomena in antiproton-proton collisions in the beam momentum range of 1.5 - 15 GeV/c. Strangeness production will be addressed through pbar p -> Hyperon-Antihyperon processes. The results of a feasibility study to measure the pbar p ->Sigmabar Lambda reaction, at antiproton beam momenta of 1.771 GeV/c and 6 GeV/c are presented and discussed in this paper.
