At the 20th International Conference on Strangeness in Quark Matter, Zaochen Ye was invited to present at one of its plenary sessions an overview of thermal dilepton measurements in heavy-ion collisions The conference typically focusses on experimental an theoretical developments with respect to strange and heavy-flavored quarks in high-energy heavy-ion collisions as well as in astrophysical phenomena. Dilepton measurements essentially straddle this range of topics as such measurements include decays of phi mesons (strangeness), contributions from charm mesons through J/psi and weak D-meson decays. Temperature measurements extracted from dilepton measurements further more give insight to the conditions inside a QGP, which is a state of matter that arose early after the Big Bang and potentially in neutron-star collisions.
