Contribution
It comprehensively summarizes existing theoretical approaches and phenomena related to quarkonia in strong magnetic fields, highlighting recent developments.
Findings
Mixing between different spin states occurs under strong magnetic fields.
Quark Landau levels lead to wave function deformation.
The quark-antiquark potential is significantly modified.
Abstract
We review the properties of quarkonia under strong magnetic fields. The main phenomena are (i) mixing between different spin eigenstates, (ii) quark Landau levels and deformation of wave function, (iii) modification of potential, and (iv) the motional Stark effect. For theoretical approaches, we review (i) constituent quark models, (ii) effective Lagrangians, (iii) QCD sum rules, and (iv) holographic approaches.
