We discuss the baryon properties under a strong magnetic field. We adopt the Skyrme model and calculate the magnetic field dependence of the mass and the pressure distribution in the soliton. We elucidate a magnetically induced contribution to the pressure sum rule and interpret it as an extra confining force. We also quantize the soliton to estimate the difference between the proton and the neutron and find a simple relation between the pressure and the mass differences.

通过变形的 Skyrmion 模拟重子限制的磁增强

我们讨论了强磁场下的重子特性。我们采用 Skyrme 模型并计算孤子中质量和压力分布的磁场依赖性。我们阐明了磁感应对压力和规则的贡献，并将其解释为额外的约束力。我们还量化孤子以估计质子和中子之间的差异，并找到压力和质量差异之间的简单关系。
