关于BPS多重子解的渐近形式及其守恒荷的注记

A remark on the asymptotic form of BPS multi-dyon solutions and their conserved charges

C. P. Constantinidis, L. A. Ferreira, G. Luchini

摘要:

我们评估的规范不变,动力学守恒的费用,最近获得的积分形式的杨米尔斯方程,BPS多双子解的杨米尔斯希格斯理论与任何紧凑的半单规范群G。这些电荷对应于希格斯场在空间无穷远处渐近形式的次首项的本征值,因此与这些解的通常拓扑电荷相吻合。这样的结果表明,在文献中考虑的许多拓扑电荷实际上是动力学电荷,其中守恒遵循经典杨-米尔斯理论的整体性质编码到其积分动力学方程。这些电荷的守恒不能从杨-米尔斯方程的微分形式得到。

英文摘要:

We evaluate the gauge invariant, dynamically conserved charges, recently obtained from the integral form of the Yang-Mills equations, for the BPS multi-dyon solutions of a Yang-Mills-Higgs theory associated to any compact semi-simple gauge group G. Those charges are shown to correspond to the eigenvalues of the next-to-leading term of the asymptotic form of the Higgs field at spatial infinity, and so coinciding with the usual topological charges of those solutions. Such results show that many of the topological charges considered in the literature are in fact dynamical charges, which conservation follows from the global properties of classical Yang-Mills theories encoded into their integral dynamical equations. The conservation of those charges can not be obtained from the differential form of Yang-Mills equations.
