# Quark-Antiquark System in Ultra-Intense Magnetic Field

@article{Simonov2012QuarkAntiquarkSI, title={Quark-Antiquark System in Ultra-Intense Magnetic Field}, author={Yu. A. Simonov and Boris Kerbikov and M. A. Andreichikov}, journal={arXiv: High Energy Physics - Phenomenology}, year={2012} }

We study the relativistic quark-antiquark system embedded in magnetic field (MF). The Hamiltonian containing confinement, color Coulomb and spin-spin interaction is derived. We analytically follow the evolution of the lowest neutral meson state as a function of MF strength. Calculating the color Coulomb energy $V_{Coul}$ we have observed the unbounded negative (at least in the limit of large $N_c$) contribution at large MF which makes the mass negative for $eB> eB^{QCD}_{crit}$. We display the…
