The Influence of Additional Semiconductor Discs on the Reconstruction of Λ Λ in the PANDA Experiment — •Simone Esch, Tobias Stockmanns, and James Ritman for the PANDA collaboration — IKP, Forschungszentrum Jülich

The PANDA detector is one of the main experiments at the upcoming Facility for Antiproton and Ion Research in Darmstadt (FAIR). The fixed target experiment will explore pp annihilation with intense, phase space cooled beams with momenta between 1.5 and 15 GeV/c. PANDA is able to measure a wide range of charmed and strange hyperons to study the dynamic of quark pair creation and hadronization. Plans exist to enlarge the acceptance of the PANDA Micro Vertex Detector in beam direction by adding two additional semiconductor discs to improve the detection of long living particles like hyperons. As a first test of these disks a simulation has been done of the physics process pp→ΛΛ→ pπ⁺ p π⁻

A comparison of the reconstruction of this channel with and without the additional disks will be presented.
