Observation of excess J/$\psi$ yield at very low transverse momenta in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}=$ 200 GeV and U+U collisions at $\sqrt{s_{\mathrm{NN}}}=$ 193 GeV

STAR Collaboration

We report on the first measurements of J/$\psi$ production at very low transverse momentum ($p_T<$ 0.2 GeV/c) in hadronic Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}=$ 200 GeV and U+U…
