In this work, we aim to increase the domain of applicability of the TPSC approach, mostly for the pseudogap region, which is important for the electron-doped cuprates. To do so, we introduce a new method, the TPSC+ approach [2]. We benchmark our results to quantum Monte Carlo simulations. We also apply this new approach to the specific case of the electron-doped cuprates in the antiferromagnetic pseudogap region of the phase diagram.
