Quarkonium at non-zero isospin density
We study the change of quarkonium bound states energies in the presence of a medium of nonzero isospin density using results from Lattice QCD and Effective field theories and solving the Schroedinger equation with the corresponding potentials. We will investigate how the medium induces a reduction of the quarkonium energies and if the reduction of the quarkonium energies becomes more pronounced as the heavy-quark mass is decreased, similar to the behaviour seen in two-colour QCD at non-zero quark chemical potential. In the process of our analysis, we will study the eta_b-pi and Upsilon-π scattering phase shifts are determined at low momentum. These findings are relevant for experiments at FAIR in Fermany and at the future Electron Ion Collider in US. Prerequisites: Quantum Mechanics I and II
