Measurement of charged Kaons in ArKCl collisions at 1.756 AGeV — •Manuel Lorenz1 and Alexander Schmah2 for the HADES collaboration — 1Frankfurt University — 2GSI Darmstadt
Charged Kaons were reconstructed from 8 · 108 Ar+KCl reactions recorded with the HADES spectrometer. Exploiting energy loss information from the time-of-flight and tracking detectors. K− could be identified with a signal to noise ratio up to S/N=4.5 and S/N=20 for K+. We present transverse mass spectra of both K+- and K−-mesons in the backward rapidity region in ArKCl-reactions at 1.756GeV/A. A differential comparison of K+/K− ratios will be discussed. This is the first high statistics analysis of charged Kaons with the HADES spectrometer installed at GSI in Darmstadt. The analysis of charged Kaons is essential for the reconstruction of the φ-meson and the full characterization of strangeness production.
