Abstract

In the introduction, we will discuss the symmetries of QCD, its breaking in the physical vacuum and its restoration at finite temperature and/or density. Then we will discuss what exact relations can be made between chiral symmetry restoration and the imaginary part of the vector vector correlation function, which is directly related to the dilepton spectrum coming from a hot and/or dense medium. Finally, we will focus on the vector meson pole appearing in the imaginary part and discuss results on how the shape changes using QCD sum rules in medium. In particular, we will discuss three characteristic changes of the vector meson peaks; namely, shift of the peak position, increase of its width and the dispersion effect due to the breaking of Lorentz invariance in medium.
