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.

Due to a high antiproton beam resolution the PANDA experiment at FAIR will offer a unique possibility to perform precise resonance energy scans. Thereby a precise line shape and width measurement of very narrow resonances like the charmonium-like X(3872), which is discussed to be exotic, becomes feasible. Monte Carlo studies have been performed, to address the achievable sensitivities of such measurements, assuming different signal cross-sections, line shapes and luminosity combinations.
