摘要:

利用QCD求和规则研究了强磁场中粲夸克团的性质。我们展示了如何实现$η_c$和$J/ψ$的混合效应的基础上的场论方法,然后表明,和规则饱和的混合效应与唯象确定的参数。因此,我们发现混合效应是强磁场中Charmonia质量漂移的主要贡献。

英文摘要:

We investigate the properties of charmonia in strong magnetic fields by using QCD sum rules. We show how to implement the mixing effects between $η_c$ and $J/ψ$ on the basis of field-theoretical approaches, and then show that the sum rules are saturated by the mixing effects with phenomenologically determined parameters. Consequently, we find that the mixing effects are the dominant contribution to the mass shifts of the charmonia in strong magnetic fields.
