Low-$p_T$ $e^+e^{-}$ pair production in Au+Au collisions and exclusive $J/\psi$ production in d+Au collisions at STAR
<!--HTML-->In ultrarelativistic heavy-ion collisions, strong electromagnetic fields arising from the Lorentz-contraction of highly charged nuclei generate a large flux of quasi-real photons. STAR measurements of the Breit-Wheeler photon-photon fusion process in Ultra-Peripheral Collisions (UPC...
