标题： Nonlinear rigid-body quantization of Skyrmions

摘要： 我们考虑在最一般的四导数广义的Skyrme模型中Skyrmion的刚体量子化，该模型包含一个给pions赋予质量的势能，以及一类高阶Skyrme模型。 首先，我们找到一种方法来量子化单个Skyrmion的自旋和同位旋零模，对应于核子，尽管该理论包含超过两个时间导数。 尽管人们可能希望一个参数族的理论在理论空间的某个点能提供更小的自旋能量修正——这将对BPS型模型是有益的，但我们发现标准的Skyrme模型产生最小的自旋能量修正，而包含超过两个时间导数的其他理论由于核子的自旋相对于标准Skyrme模型增加了动能。 我们推测这种自旋能量的调整是否在量子化Skyrmion的振动和轻质量模式的更大图景中有用。 显示英文摘要

摘要： We consider rigid-body quantization of the Skyrmion in the most general four-derivative generalization of the Skyrme model with a potential giving pions a mass, as well as in a class of higher-order Skyrme models. First of all, we find a way to quantize the spin and isospin zeromodes of the single Skyrmion corresponding to the nucleon, even though the theory contains more than two time derivatives. Although one could hope that a one-parameter family of theories could provide a smaller spin correction to the energy at some point in theory space - which would be welcome for BPS-type models, we find that the standard Skyrme model gives rise to the smallest spin correction to the energy and the other theories with more than two time-derivatives increase the kinetic energy due to the spin of the nucleon with respect to the standard Skyrme model. We speculate whether this tuning of the spin energy could be useful in the larger picture of quantizing vibrational and light massive modes of the Skyrmions.
