Particle-identification capability of the straw tubetracker and
feasibility studies for the charmedbaryonprogram with P̄ANDA

PANDA will be one of the key experiments at the future Facility for Antiproton and Ion Research (FAIR), which is under construction in Darmstadt, Germany. The PANDA experiment will explore collisions of an antiproton beam with a fixed proton or nuclear target.PANDA has a unique setup among other physics experiments and it will provide unique access to the various physics topics. The PANDA experiment is expected to provide new results to help experimentally map out the heavy-baryon sector. The Λc baryon plays a significant role in understanding both charm and bottom baryons. PANDA has four main tracking detectors and one of them is the Straw Tube Tracker (STT), a cylindrical-shaped detector consisting of gas-filled tubes. The tasks of the STT are to determine the momenta of charged particles, via a precise spatial reconstruction of particle tracks in combination with a solenoid magnetic eld, and to perform particle identification (PID) by measuring the specific energy loss.

This thesis presents Monte Carlo (MC) simulations which performed to investigate the capability of PANDA in charmed baryon production. In addition, the results of tests performed with a prototype STT detector are presented to investigate the electronic readout and tracking and PID performance, as well as to eventually make a decision for the readout of the PANDA STT detector.
