Study of charm and beauty in QGP from unquenched lattice QCD

We present charmonium and bottomonium correlators and corresponding reconstructed spectral functions from full QCD calculations in the pseudoscalar channel. Correlators are obtained using a mixed-action approach, clover-improved Wilson valence quarks on gauge field configurations generated with 𝑁 𝑓 = 2 + 1 HISQ sea quarks, with physical strange quark masses and light quark masses corresponding to 𝑚 𝜋 = 315 MeV. The charm and bottom quark masses are tuned to reproduce the experimental mass spectrum of the spin averaged quarkonium vector mesons from the particle data group [1]. For the spectral reconstruction, we use models based on perturbative spectral functions from different frequency regions like resummed thermal contributions around the threshold from pNRQCD [2] and vacuum contributions well above the threshold [3]. We show preliminary results of the reconstructed spectral function obtained for the first time in our study for full QCD.
