Four-Dimensional Effective Supergravity and Soft Terms in M-Theory

Kiwoon Choi, Hang Bae Kim, Carlos Munoz

We provide a simple macroscopic analysis of the four-dimensional effective supergravity of the Hořava-Witten M-theory which is expanded in powers of ${\kappa }^{2/3}/\rho V^{1/3}$ and $κ^{2/3}…
