超对称P(X,phi)与幽灵凝聚

Supersymmetric P(X,phi) and the Ghost Condensate

Justin Khoury, Jean-Luc Lehners, Burt Ovrut

摘要:

我们展示了如何在d=4,N=1的超对称性的背景下,构造形式为P(X,φ)的高阶导数标量场理论的超对称作用。这种构造是通用的,并且被应用于写出狄拉克-玻恩-因菲尔德作用量的超对称版本。我们的主要应用是构造鬼凝聚的超对称扩张。这使我们能够研究超对称性,时间相关的背景和违反零能量条件之间的相互作用。

英文摘要:

We show how to construct supersymmetric actions for higher-derivative scalar field theories of the form P(X,phi), within the context of d=4, N=1 supersymmetry. This construction is of general use, and is applied to write supersymmetric versions of the Dirac-Born-Infeld action. Our principal application of this formalism is to construct the supersymmetric extension of the ghost condensate. This allows us to study the interplay between supersymmetry, time-dependent backgrounds and violations of the null energy condition.
