摘要

我们研究了一个散射过程，在这个过程中，一组粒子聚集在一起，通过像膨胀介导的远程无质量标量力相互作用，然后分散。利用世界线的形式，我们计算了散射粒子的运动轨迹，并在标量波形的晚时和早时展开中导出了无限级数的子导项。研究了标量波形、标量存储项和经典软标量定理。我们忽略了引力相互作用，如果我们把它们包括进来，我们就会讨论其中的挑战。

Waveform, memory and classical soft scalar theorems

We examine a scattering process in which a set of particles come together, interact through a long-range massless scalar force like dilaton mediated and then disperse. Using worldline formalism, we compute the trajectories of the scattered particles and derive an infinite series of subleading terms in the late-time and early-time expansion of the scalar waveform. We study the scalar waveform, the scalar memory term and classical soft scalar theorems. We ignore gravitational interactions and discuss the challenges if we include them.

期刊介绍： Nuclear Physics B focuses on the domain of high energy physics, quantum field theory, statistical systems, and mathematical physics, and includes four main sections: high energy physics - phenomenology, high energy physics - theory, high energy physics - experiment, and quantum field theory, statistical systems, and mathematical physics. The emphasis is on original research papers (Frontiers Articles or Full Length Articles), but Review Articles are also welcome.
