abstract = {We report a high-precision numerical estimation of the critical exponent {\$}\backslashalpha{\$} of the specific heat of the random-field Ising model in four dimensions. Our result {\$}\backslashalpha = 0.12(1){\$} indicates a diverging specific-heat behavior and is consistent with the estimation coming from the modified hyperscaling relation using our estimate of {\$}\backslashtheta{\$} via the anomalous dimensions {\$}\backslasheta{\$} and {\$}\backslashbar{\{}\backslasheta{\}}{\$}. Our analysis benefited form a high-statistics zero-temperature numerical simulation of the model for two distributions of the random fields, namely a Gaussian and Poissonian distribution, as well as recent advances in finite-size scaling and reweighting methods for disordered systems. An original estimate of the critical slowing down exponent {\$}z{\$} of the maximum-flow algorithm used is also provided.},
