摘要:

利用一个分量公式,我们构造了三维Newton-Cartan超引力背景中超粒子的超对称作用量,并阐明了它的对称性。我们的构建首先在平坦的背景中构建超粒子。接下来,通过增强背景对称性,我们在第一步中用伽利略超引力背景代替平坦背景。在第二步中,伽利略超引力背景被牛顿-嘉当超引力背景所取代。我们通过增加一个超对称宇宙学常数来扩展我们的结果,并将非相对论性超粒子与相对论性κ对称三维超粒子进行了比较。

英文摘要:

Using a component formulation, we construct the supersymmetric action for a superparticle in a three-dimensional Newton-Cartan supergravity background and clarify its symmetries. Our construction proceeds by first constructing the superparticle in a flat background. Next, by boosting up the background symmetries, we replace in a first step the flat background by a Galilean supergravity background. In a second step the Galilean supergravity background is replaced by a Newton-Cartan supergravity background. We extend our results by adding a supersymmetric cosmological constant and compare the non-relativistic superparticle with the relativistic kappa-symmetric three-dimensional superparticle.
