This article reviews the current status of experimental results obtained in the measurement of light vector mesons produced in proton-proton and heavy ion collisions at different energies. The review is focused on two phenomena related to the light vector mesons; the modification of the spectral shape in search of chiral symmetry restoration and suppression of the meson production in heavy ion collisions. The experimental results show that the spectral shape of light vector mesons are modified compared to the parameters measured in vacuum. The nature and the magnitude of the modification depends on the energy density of the media in which they are produced. The suppression patterns of light vector mesons are different from the measurements of other mesons and baryons. The mechanisms responsible for the suppression of the mesons are not yet understood. Systematic comparison of existing experimental results points to the missing data which may help to resolve the problem.

• Hadronic molecules (2017, background): “…the near degeneracy of, e.g., D∗ and D as well as B∗ and B. Similarly, it also predicts straightforwardly multiplets of hadronic molecules made of a heavy hadron or heavy quarkonium and light hadrons (Guo et al., 2009a; Yamaguchi et al., 2015), and of hadroquarkonium as well (Cleven et al., 2015).”
