我们研究了磁背景下具有量子手性异常的重子的Skyrme模型，并提出重子内部可能产生一种新的电荷结构。由于异常诱导的测量weiss - zuma项，Skyrmions给出的局部介子凝聚将在背景磁场中产生局部电荷源。由于重子上总附加电荷的出现看起来既不现实又令人惊讶，我们讨论了我们对异常效应的详细评估的有效性。
We study the Skyrme model of baryons with quantum chiral anomaly of QCD in magnetic backgrounds, and suggest a possible induction of a novel structure of electric charge inside the baryons. Due to the anomaly-induced gauged Wess-Zumino term, the Skyrmions giving a local pion condensationwould produce a local charge source, in the background magnetic field. Since the appearance of the total additional electric charge on the baryon looks unrealistic and surprising, we discuss the validity of our detailed evaluation of the anomaly effects.
