超对称Yang-Mills理论中的可解相对论类氢体系

Solvable Relativistic Hydrogenlike System in Supersymmetric Yang-Mills Theory

Simon Caron-Huot, Johannes M. Henn

摘要:

经典的开普勒问题,以及它的量子力学版本,氢原子,享有一个众所周知的隐藏对称性,拉普拉斯-龙格-伦茨矢量守恒,这使得这些问题超可积。有没有一种相对论性的量子场论扩展能保持这种对称性?在这封信中,我们表明,答案是肯定的:在非相对论性的限制,我们确定的对偶共形对称的平面$\mathcal{N}=4$超级杨米尔斯与众所周知的对称性的氢原子。指出对偶共形对称性为理论上计算有质量$W$玻色子的束缚态谱提供了一种新的方法。我们在弱耦合和强耦合下对该设置进行了非平凡测试,并对可能扩展到任意耦合值的情况进行了评论。

英文摘要:

The classical Kepler problem, as well as its quantum mechanical version, the Hydrogen atom, enjoy a well-known hidden symmetry, the conservation of the Laplace-Runge-Lenz vector, which makes these problems superintegrable. Is there a relativistic quantum field theory extension that preserves this symmetry? In this Letter we show that the answer is positive: in the non-relativistic limit, we identify the dual conformal symmetry of planar $\mathcal{N}=4$ super Yang-Mills with the well-known symmetries of the Hydrogen atom. We point out that the dual conformal symmetry offers a novel way to compute the spectrum of bound states of massive $W$ bosons in the theory. We perform nontrivial tests of this setup at weak and strong coupling, and comment on the possible extension to arbitrary values of the coupling.
