矢量介子稳定的小Skyrmions

Baby Skyrmions stabilized by vector mesons

David Foster, Paul Sutcliffe

摘要:

最近的研究结果表明,多Skyrmions稳定的Ω介子有非常相似的性质,稳定的Skyrme项。在本文中,我们提出了一个详细的数值研究的结果(2+1)维模拟这种情况。也就是说,我们计算了耦合到大质量矢量介子的O(3)σ模型中的孤子,并将结果与包含Skyrme项的O(3)σ模型中的婴儿Skyrmions孤子进行了比较。我们发现矢量介子模型中的多孤子与婴儿Skyrme模型中的多孤子有着惊人的相似之处,我们用一个简单的导数展开来解释这种对应关系。

英文摘要:

Recent results suggest that multi-Skyrmions stabilized by omega mesons have very similar properties to those stabilized by the Skyrme term. In this paper we present the results of a detailed numerical investigation of a (2+1)-dimensional analogue of this situation. Namely, we compute solitons in an O(3) sigma-model coupled to a massive vector meson and compare the results to baby Skyrmions, which are solitons in an O(3) sigma-model including a Skyrme term. We find that multi-solitons in the vector meson model are surprisingly similar to those in the baby Skyrme model, and we explain this correspondence using a simple derivative expansion.
