解构超引力:大质量超多重态

Deconstructing Supergravity: Massive Supermultiplets

Nicholas A. Ondo, Andrew J. Tolley

摘要:

鉴于解构程序在从5-D爱因斯坦引力中获得无幽灵大质量引力方面的成功,我们提出了一个在线性水平上结合超对称性的解构程序的修改。本文讨论了自旋为2的大质量超多重态的束缚相互作用理论的有关极限,确定了该线性理论是Fierz-Pauli理论的超对称推广,即N=1的Zinoviev理论.我们开发了一个家庭的1-站点解构程序的费米子场(产生狄拉克和马约拉纳质量条款)。适当的解构程序,使费米子狄拉克质量被发现保持一半的5-D理论的超对称性。我们通过将5维N=2超麦克斯韦理论解构为4维N=1超普罗卡理论,将线性5维N=2超引力解构为4维N=1季诺维也夫理论,并分别从5维超代数和规范对称性导出完整的4维超对称性代数和施托克伯格对称性,来明确地检验这一点。我们猜想,这一过程应承认一个推广到完全非线性理论。

英文摘要:

Given the success of the deconstruction program in obtaining ghost-free massive gravity from 5-D Einstein gravity, we propose a modification of the deconstruction procedure that incorporates supersymmetry at the linear level. We discuss the relevant limits of a conjectured interacting theory of a massive spin 2 supermultiplet, and determine the linear theory to be the N=1 Zinoviev theory, a supersymmetric extension of Fierz-Pauli theory. We develop a family of 1-site deconstruction procedures for fermionic fields (yielding Dirac and Majorana mass terms). The deconstruction procedure appropriate for giving fermions a Dirac mass is found to preserve half of the supersymmetry of the 5-D theory. We explicitly check this by deconstructing 5-D N=2 super-Maxwell theory down to 4-D N=1 super-Proca theory, and deconstructing linear 5-D N=2 supergravity down to 4-D N=1 Zinoviev theory, and derive the full 4-D supersymmetry algebras and Stueckelberg symmetries from the 5-D superalgebras and gauge symmetries, respectively. We conjecture that this procedure should admit a generalization to fully non-linear theories.
