The Bak-Tang-Weisenfeld sandpile model in scale-free networks was studied. Numerical simulations revealed that for 2<γ<3 the scaling behavior of the avalanche size distribution differs from the mean-field prediction. By mapping to the multiplicative branching process, it was possible to obtain the asymptotic behaviors of the avalanche size and duration distributions analytically.
