超对称黑环与非线性西格玛模型

Supersymmetric black rings and non-linear sigma models

Yi-Xin Chen, Yong-Qiang Wang

摘要:

本文研究了将D = 5超引力简化为D = 3时产生的非线性西格玛模型,并介绍了该西格玛模型在五维最小超引力超对称黑环解中的应用。通过对$R \times U(1)\times U(1)$等距定态解的分析,得到了陪集$G_{2(+2)}/SO(4)$上弦状物体测地运动的二维拉格朗日量,并研究了超对称黑环的守恒荷代数和超对称约束.我们还得到了超对称黑环的半经典波函数。

英文摘要:

In this paper we investigate the non-linear sigma model arising in the reduction of D = 5 supergravity to D = 3, and present the application of this sigma model to supersymmetric black ring solutions in five-dimensional minimal supergravity. With the ansatz of stationary solutions with $R \times U(1)\times U(1)$ isometry, we obtain a two-dimensional Lagrangian corresponding to geodesic motion of a string-like object on the coset $G_{2(+2)}/SO(4)$, and study the algebra of conserved charges and supersymmetry constraints of supersymmetric black rings. We also obtain the semi-classical wave function of supersymmetric black rings.
