Abstract. Fibre inflation model, proposed in the framework of LARGE volume scenarios, is one of most attractive inflationary models in which not only the moduli stabilization studies are fairly established but also one has a good control over the (un-)known sub-leading corrections to trust the EFT description. In this talk, I will present some explicit Calabi Yau orientifold examples which could be minimally sufficient for the global embedding of Fibre inflationary potential. The main idea is to find suitable K3-fibred Calabi Yau threefolds, and then choose orientifold involutions such that the tadpole/anomaly cancellations conditions could be satisfied, and the desired form of string-loop corrections to the Kaehler potential as well as the non-perturbative corrections to the superpotential are ensured to get generated. Subsequently, the final task is to perform the numerical analysis for fitting the inflationary observables, and to check for the overall control, e.g. to ensure that the higher derivative contributions do not spoil the inflationary dynamics.
