Performance qualitative study of the P ̅ANDA GEM-tracker in the physics simulation

One of the most challenging and exciting goals of modern physics is to achieve good and quantitative understanding of the strong interaction. Significant progress is achieved in recent years, all thanks to the remarkable progress in the study of empirical and speculative. Tentatively, study about hadron structure can be done by electrons, pions, kaons, protons and antiprotons. Antiprotons are excellent tools to inspect the antiprotons-protons annihilation problems, a particle with gluonic degrees of freedom and particle and antiparticle pair which are produced repeatedly, and also allow spectroscopy studying with very high precision and statistics. In order to identify more such as these cases, P ̅ANDA experiment is designed to be completely extraordinary physical potential due to exploit the availability of cold and high-intensity beams of antiprotons. So, for more understanding and study of high-energy physics and strong interactions, P ̅ANDA experiment is designed. One of the significant parts of the P ̅ANDA set-up is gas electron multiplayer tracking systems which are under studying and construction. In this article is tried to demonstrate the influence of one typical kind of these systems in order to improve precise particles mass measurement, tracking efficiency and momentum resolution.
