Description
In this work, we employ a field-theoretic renormalization group approach to study a paradigmatic model of directed percolation. We focus on the perturbative calculation of the equation of state, extending the analysis to the three-loop order in the expansion parameter $\varepsilon = 4-d$. The main aims of this study are to provide an update on this ongoing work and to present the numerical technique developed for the necessary calculations. We verify existing two-loop results and enumerate the complete set of Feynman diagrams necessary for the three-loop calculation.
