Effect of shock acceleration, stochastic acceleration, and both accelerations combined (in different panels) on steady state densities N′ for muons, pions, and kaons. Here, the burst SB from Table 1, η_I = 0.1, and η_II = 2.5 have been used. The different panels are for acceleration in the shock (left), in the radiation zone (middle), and both (right). Here, Kolmogorov diffusion has been used as transport mechanism between the two zones. The dashed curves are shown without acceleration for comparison.
