We have obtained new runs at am_q=0.025 and improved runs at am_q=0.0125. The results are extrapolated to m_q=0, and we extract the speed of sound as well. We also present evidence for a restoration of the SU(2) X SU(2) chiral symmetry just above the crossover, but not of the axial U(1) chiral symmetry. ## Full text _Full body text omitted from this summary view._ Fetch the complete paper as Markdown: https://tomesphere.com/paper/hep-lat/9608026/full.md ## Figures 5 figures with captions in the complete paper: https://tomesphere.com/paper/hep-lat/9608026/full.md ## References 11 references — full list in the complete paper: https://tomesphere.com/paper/hep-lat/9608026/full.md --- Source: https://tomesphere.com/paper/hep-lat/9608026
