Deuteron emission from Ag+Ag Collisions at 1.58A GeV — •Carl-Philipp Roy for the HADES collaboration — Goethe-Universität Frankfurt

A high statistics data sample of Ag(1.58A-GeV)+Ag events recorded in scope of the FAIR phase 0 program in March 2019 is used to study multi-differential emission rates of deuteron.
In this contribution, we discuss details of the extraction of deuteron signals from the bulk of reconstructed charged particle tracks. The extracted deuteron signals are corrected with simulated detector response coefficients and then used to calculate the multi-differential emission rate per event as a function of transverse mass and center- of-mass rapidity. The obtained phase-space distribution of deuteron yields is fitted with thermally motivated model functions and extrapolated to phase-space not covered by the detector geometry. The results are discussed in context of available world data.
