New effect in wave-packet scattering of quantum fields

|
By Kin-ya Oda, Kenzo Ishikawa, Kenji Nishiwaki, Woman’s Christian
| Physical Review B
We report calculations of a wave-packet amplitude of the two-body scattering ϕϕ→Φ→ϕϕ, which leads to the measured probability in realistic experiments. We elucidate the decay amplitude of Φ→ϕϕ from this. In such an amplitude of wave packets, there are in and out time boundaries for the initial Φ and final ϕϕ configurations, respectively. In this paper, we prove that the effect of the in time boundary of Φ→ϕϕ emerges from ϕϕ→Φ→ϕϕ without assuming any time boundary a priori.
