Abstract	Phi meson production is studied by the NA49 collaboration in central Pb+Pb collisions at 20A, 30A, 40A, 80A and 158A GeV beam energy. The data are compared to measurements at lower and higher energies and to microscopic and thermal models. The energy dependence of yields and spectral distributions is compatible with the assumption that partonic degrees of freedom set in at low SPS energies.

(a) Mean $dE/dx$ as function of $\beta\gamma$ determined for TOF-identified pions, kaons, and protons; (b) $dE/dx$ resolution as function of momentum, obtained from the deconvolution of the energy loss spectra into thecontributions of $\pi^+$, $K^+$, and $p$.$ $(Color online) $dE/dx$ parametrization for the data set at 80$A$~GeV.
