Energy transmission across conformal interfaces between 2D CFTs is universal, the transmission coefficients do not depend on the shape and composition of the wave packet. Transmission and reflection coefficients can be computed and expressed in terms of interface CFT parameters via holographic methods. In higher dimensions the situation becomes much richer and more involved. I will present work in progress on computing energy transmission across interfaces in higher dimensional CFTs and comment on recent results for head-on collisions in general higher dimensions.
