连续自旋粒子理论:波函数和软因子散射振幅

On the Theory of Continuous-Spin Particles: Wavefunctions and Soft-Factor Scattering Amplitudes

Philip Schuster, Natalia Toro

摘要:

庞加莱不变性所允许的最普遍的无质量粒子是“连续自旋”粒子(CSP),其特征是尺度为ρ,在ρ=0时,它简化为熟悉的螺旋粒子。虽然已知的长程力已使用螺旋粒子充分模拟,但尚不清楚CSP是否也可以介导长程力或这种力可能产生的后果。我们提出了尖锐的证据CSP与物质的相互作用一致:新的CSP运动方程,波函数和协变辐射振幅。在配套文件中,我们使用这些结果来解决有关CSP热力学的老难题,并表现出显着的对应限制CSP振幅接近螺旋度-0,1或2振幅。

英文摘要:

The most general massless particles allowed by Poincare-invariance are "continuous-spin" particles (CSPs) characterized by a scale ρ, which at ρ=0 reduce to familiar helicity particles. Though known long-range forces are adequately modeled using helicity particles, it is not known whether CSPs can also mediate long-range forces or what consequences such forces might have. We present sharp evidence for consistent interactions of CSPs with matter: new CSP equations of motion, wavefunctions, and covariant radiation amplitudes. In a companion paper, we use these results to resolve old puzzles concerning CSP thermodynamics and exhibit a striking correspondence limit where CSP amplitudes approach helicity-0, 1 or 2 amplitudes.
