摘要：

The dissatisfactory results provided by various transport models to HADES Au+Au collisions have prompted a novel approach to the description of particle spectra. The use of statistical-hadronisation-based models is proposed. In addition, a unique freeze-out hypersurface parametrisation is emplyed, which, with few kinematic parameters, is able to describe spectra of most abundant particles produced in the Au+Au root SNN = 2.4 GeV most central collisions. A femtoscopic correlation study of identical pions is showcased with moderate reproduction.
