Llanes Estrada, Felipe José ; Torres Rincón, Juan Miguel ; Cabrera Urban, Daniel | Academic Press Inc Elsevier Science | 2011-10We compute the charm drag and diffusion coefficients in a hot pion gas, such as is formed in a heavy ion collision after the system cools sufficiently to transit into the hadron phase. We fully exploit heavy quark effective theory (with both D a[...]texto impreso
