Abstract.  We present an overview on one issue of practical interest for burning plasmas; i.e., whether fast ions and charged fusion products are sufficiently well confined that they transfer their energy and/or momentum to the thermal plasma without appreciable degradation due to collective modes. In the present work, we analyze this problem starting from its first principle theoretical grounds, i.e. the identification of key physics in burning plasma stability properties as well as the non-linear dynamics above threshold. We also discuss the investigations of such processes via computer simulations as well as the importance of benchmarking with existing or future experimental observations. * This work is supported by U.S. D.o.E.
