The upcoming PANDA experiment at FAIR will be one among a new generation of experiments
making use of a fully-software based trigger system where PID and tracking will play main roles. The
high data rate of up to 200 GB/s implies a need to reduce the amount of data by a factor of up to
1000, which in turn puts high demands on the online tracking algorithms.
Hyperon physics will be one of the main pillars of the PANDA experimental program from the
start of the experiment. The trigger system therefore needs to be able to recognize certain hyperon
channels, mainly based on tracking. One of the main challenges of tracking hyperons is their relatively
long lifetime which makes them decay a measurable distance from the interaction point.
In this report, the tracking detectors of PANDA, the software framework as well as some tracking
algorithms are discussed. The report also maps out the behavior of the main decay products of
the hyperons in the reactions $\bar{p}p\rightarrow\bar{\Lambda}\Lambda$, $\bar{p}p\rightarrow\bar{\Xi}^+\Xi^-$
and $\bar{p}p\rightarrow\bar{\Omega}^+\Omega^-$ in the target spectrometer
of PANDA and the detector signatures of the final state particles. Conclusions are drawn on how
to proceed to develop the most eficient online tracking and event reconstruction possible for these
channels at PANDA.
