Descripción
The PANDA experiment is one of the major projects at the Facility for Antiproton and Ion Research (FAIR) and will study a wide range of physics topics with beams of antiprotons incident on fixed proton or complex nuclei targets. One of the interesting issues is the Ds semileptonic decay, which is governed by both the weak and strong forces. Here the strong interaction effects can be parameterized by the transition form factor. Techniques such as lattice QCD offer increasingly precise calculations, but as the uncertainties shrink, experimental validation of the results becomes increasingly important. The achievable performance of the full PANDA detector for these types of reactions has not yet been studied in detail; however, this is expected to work very well based upon the design performance and experience with similar detector systems.
This poster summarizes the simulation and reconstruction of the Ds decay chain. In the reconstruction procedure, we focus on modeling properly the decay process and evaluating the expected precision of these measurements with the full PANDA detector. The required models in this decay chain are corroborated via Dalitz plot analysis. The present version of EvtGen in PandaRoot has been enhanced by a new model describing the Ds→KKπ decay. The reconstruction efficiency and resolutions have been studied for the proposed decay chain. With the help of theoretical predictions of the cross section, the event reconstruction rate is estimated.
