四维平坦空间中的无质量高自旋立方顶点

Massless higher spin cubic vertices in flat four dimmensional space

M. V. Khabarov, Yu. M. Zinoviev

摘要:

本文构造了四维平坦空间中无质量玻色子和费米子高自旋场的立方相互作用顶点。首先,我们在AdS_4空间中用一种所谓的Fradkin-Vasiliev方法构造了这些立方顶点,这种方法只适用于非零的宇宙学常数。然后,我们考虑一个平坦的限制照顾所有的高导数项的FV方法产生。我们把自己限制在四维空间,因为这使我们能够使用框架式的多旋量形式主义,它大大简化了所有的计算,并在平等的基础上提供了对玻色子和费米子的描述。

英文摘要:

In this paper we construct a number of cubic interaction vertices for massless bosonic and fermionic higher spin fields in flat four dimensional space. First of all, we construct these cubic vertices in AdS_4 space using a so-called Fradkin-Vasiliev approach, which works only for the non-zero cosmological constant. Then we consider a flat limit taking care on all the higher derivative terms which FV-approach generates. We restrict ourselves with the four dimensions because this allows us to use the frame-like multispinor formalism which greatly simplifies all calculations and provides a description for bosons and fermions on equal footing.
