Simulation Studies of the Lambda Disks Detector for the PANDA Experiment

Abstract

(formula presented) is one of the major experiments at the future accelerator facility FAIR which is currently under construction in Darmstadt, Germany. The goal of (formula presented) is mainly to explore the non-perturbative regime of QCD and to study hadronic states including hyperon states. Most of the hyperon ground states have decay lengths of several centimeters, but the central tracking system of (formula presented) is not optimized for such decay lengths. Therefore, an upgrade option is proposed, adding two additional silicon sensor disks in forward direction in front of the innermost tracking detector of (formula presented), the MVD. These additional disks are called “Lambda Disks Detector ”. For this new detector, simulation studies were performed for the reaction (formula presented). In this paper, the reconstruction efficiency and resolution of this channel are presented under the hypothesis that the Lambda Disks Detector is added to the (formula presented) setup. In addition, (formula presented) and (formula presented) channels are studied to see how the reconstruction performance of these channels is affected with and without the Lambda Disks Detector. © 2018, Springer International Publishing AG, part of Springer Nature.
