Abstract
This contribution covers the emission of charged pions, measured by the HADES (High-Acceptance-Di-Electron-Spectrometer) detector in March 2019, for the collision system Ag+Ag with a center-of-mass energy of √sNN=2.55 GeV. After a brief motivation, the experimental set-up of HADES is summarized and the basic analysis steps concerning the identification of charged pions, acceptance and efficiency correction and extrapolation into uncovered phase space regions are explained. Within this context, the obtained transverse mass spectra are presented. The last part covers azimuthal emission anisotropies relative to the event plane of the collisions. The employed method for extracting the flow harmonics of charged pions is described and the harmonics v1 and v2 are inspected as a function of transverse momentum and rapidity.
