Kerr-Schild几何的扭量弦结构与Dirac-Kerr系统的相容性

Twistor String Structure of the Kerr-Schild Geometry and Consistency of the Dirac-Kerr System

Alexander Burinskii

摘要:

旋转黑洞和自旋粒子的Kerr-Schild(KS)几何是基于与Kerr定理相关联的扭量结构,该扭量结构由射影扭量空间$Z \in CP^3 .$中的解析曲线$F(Z)=0$定义。有一个复杂的纽曼表示,它将克尔-纽曼解的源描述为沿着复杂的世界线$X(\t)\in CM^4,$传播的“粒子”,这个世界-复世界线实际上是一个世界片,$F(Z).$,克尔源可以被认为是在虚时间方向上扩展的复欧几里德串$σ$。克尔扭量结构原来是毗邻克尔复杂的字符串源,形成一个自然的扭量字符串结构类似的奈尔-威滕扭量字符串。我们表明,扭转极化的克尔-纽曼解决方案可以匹配的{ \it无质量}的狄拉克方程的解决方案,提供的狄拉克-克尔模型的自旋粒子(电子)的一致性。它使我们能够扩展奈尔-威滕关于扭量空间中规范振幅散射的概念,使之包括大质量KS粒子。

英文摘要:

Kerr-Schild (KS) geometry of the rotating black-holes and spinning particles is based on the associated with Kerr theorem twistor structure which is defined by an analytic curve $F(Z)=0$ in the projective twistor space $Z \in CP^3 .$ On the other hand, there is a complex Newman representation which describes the source of Kerr-Newman solution as a "particle" propagating along a complex world-line $X(\t)\in CM^4,$ and this world-line determines the parameters of the Kerr generating function $F(Z).$ The complex world line is really a world-sheet, $\t= t + i σ,$ and the Kerr source may be considered as a complex Euclidean string extended in the imaginary time direction $σ$. The Kerr twistor structure turns out to be adjoined to the Kerr complex string source, forming a natural twistor-string construction similar to the Nair-Witten twistor-string. We show that twistor polarization of the Kerr-Newman solution may be matched with the {\it massless} solutions of the Dirac equation, providing consistency of the Dirac-Kerr model of spinning particle (electron). It allows us to extend the Nair-Witten concept on the scattering of the gauge amplitudes in twistor space to include massive KS particles.
