Melting of P wave bottomonium states in the quark-gluon plasma from lattice NRQCD

Understand

We study the fate of P wave bottomonium states in the quark-gluon plasma, using a spectral function analysis of euclidean lattice correlators.

• The correlators are obtained from lattice QCD simulations with two light quark flavours on highly anisotropic lattices, treating the bottom quark nonrelativistically.
• We find clear indications of melting immediately after the deconfinement transition.
