PANDA Management Quarterly Report 19Q3

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.

PANDA Management Quarterly Report 19Q2

The PANDA detector at the international accelerator Facility for Antiproton and Ion Research in Europe (FAIR) in Darmstadt (Germany)
will address fundamental questions of hadron physics in high-energy antiproton collisions with fixed hydrogen and nuclear targets. 

The PANDA Forward RICH (FRICH) is intended for identification of charged particles with forward polar angles below 5°–10°
and momenta from 3 to 15 GeV/c. PANDA FRICH will have a multilayer focusing aerogel radiator to achieve the required
resolution on Cherenkov angle. A set of precisely aligned flat mirrors will collect light on the multi-anode photomultipliers
which are located outside of the detector’s effective aperture. A baseline design of the PANDA Forward RICH is presented including results
of the full Monte-Carlo simulation, optical measurements and prototype beam tests.
