一个无质量两个等质量粒子的非BPS超对称3pt振幅

Non-BPS Supersymmetric 3pt Amplitude for One Massless, Two Equally Massive Particles

Bo-Ting Chen

摘要:

在本文中,非BPS振幅($Z < 2m$)被认为是。利用在壳层方法,构造了两个等质量粒子和一个无质量粒子的三点振幅,其中两个粒子都是非BPS态。通过将$Z = 0$和BPS极限与$N = 2$超对称性进行匹配,验证了这一结果.作为应用,我们导出了$N = 4$超麦克斯韦和超引力的非BPS耦合。

英文摘要:

In this paper, the non-BPS amplitudes ($Z < 2m$) are considered. Utilizing on-shell methods, the three point amplitudes of two equal-mass particles and one massless particle were constructed, where the two massive particles are non-BPS states. We verify the result by matching the $Z = 0$ and BPS limit with $N = 2$ supersymmetry. As an application we derive the non-BPS coupling for $N = 4$ super-Maxwell and supergravity.
