“…As a result we have the eikonal representation of elastic scattering amplitude with eikonal phase function χ 0 (|r ⊥ |, s) in Eq. (31). It is important note that the nonlocal potential differs from the local by terms of order O 1 p in the high energy limit p → ∞.…”

“…Use this exact form of the Yukawa as a quasi-potential and replace into Eqs. (29) and (30), for the leading eikonal amplitude and its first correction, we get (see Appendix C)…”

“…When substituting the Newtonian potential (40) into Eqs. (29) and (30), the vertex factor for graviton exchange between "nucleons" should be added by V Newton with sV Newton [21,62], the definition of the non-relativistic potential (see Eq. (D.7) in Appendix D) and graviton still has a mass μ and perform some calculations for the leading eikonal behavior and the first correction of the scattering amplitude (see Eqs.…”

“…An approach that has probed the first of these features with some success is the one that based on the reggeized string exchange amplitudes with subsequent reduction to the gravitational eikonal limit including the leading order corrections [18]. In articles [19][20][21] the high energy scattering amplitude of two "nucleons" in the quantum gravity is constructed by extending the functional integration method [22][23][24][25][26][27][28] which has been used effectively in quantum electrodynamics [29][30][31][32][33][34][35][36][37][38]. A straightline path approximation was used to calculate the functional integrals which occur.…”
The asymptotic behavior of the scattering amplitude for two scalar particles at high energies with fixed momentum transfers is studied. The study is done within the effective theory of quantum gravity based on quasi-potential equation. By using the modified perturbation theory, a systematic method is developed to find the leading eikonal scattering amplitudes together with corrections to them in the one-loop gravitational approximation. The relation is established and discussed between the solutions obtained by means of the operator and functional approaches applied to quasi-potential equation. The first non-leading corrections to the leading eikonal amplitude are found.
