Spacetime curvature corrections for the Yukawa potential and its application for the Reissner-Nordström Metric

J. V. Zamperlini, C. C. Barros

In this paper, we investigate the influence of the spacetime curvature on the Yukawa potential, focusing on boson-boson interactions derived from the {Φ^3} theory. Using the Bunch…
