High energy scattering amplitude in the linearized gravitational theory

Do Thu Ha

摘要:

在线性化引力理论的Logunov-Tavkhelidze方程中,重新考虑了两个高能标量粒子之间的引力子交换和固定动量转移引起的弹性散射振幅的渐近行为.利用高能区的主要贡献,发展了相对阶准势方法$1/p$中程函近似的修正。导出了散射振幅的程函表达式和形式一次修正。应用汤川势对结果进行了讨论。

英文摘要:

The asymptotic behavior of the elastic scattering amplitude by the exchange of graviton between two scalar particles at high energies and fixed momentum transfers is reconsidered in the Logunov-Tavkhelidze equation in the linearized gravitational theory. The corrections to the eikonal approximation in the quasi-potential approach of relative order $1/p$ is developed with the principal contributions at high energy. The eikonal expression of scattering amplitude and the formal first correction are derived. The Yukawa potential is applied to discuss the results.
