边缘双子衰变的运动学模拟

Kinematical Analogy for Marginal Dyon Decay

Anindya Mukherjee, Sunil Mukhi, Rahul Nigam

摘要:

我们描述了在四维N=4弦紧化中1/4-BPS双子的边缘衰变的运动学类比。在这个类比中,电荷和磁荷扮演空间动量的角色,BPS质量扮演能量的角色,而1/2-BPS双子对应于无质量的粒子。利用SO(12,1)“Lorentz”不变性和粒子物理学中的标准运动学公式,给出了临界稳定性曲线的简单推导。我们还展示了这些曲线如何映射到动量椭球,并提出了这种类比的一些应用。

英文摘要:

We describe a kinematical analogy for the marginal decay of 1/4-BPS dyons in 4-dimensional N=4 string compactifications. In this analogy, the electric and magnetic charges play the role of spatial momenta, the BPS mass plays the role of energy, and 1/2-BPS dyons correspond to massless particles. Using SO(12,1) "Lorentz" invariance and standard kinematical formulae in particle physics, we provide simple derivations of the curves of marginal stability. We also show how these curves map into the momentum ellipsoid, and propose some applications of this analogy.
