Description
With the advent of the string landscape, the realisation of the Standard Model in general string theory compactifications to 4D has become a primary focus. This talk concerns novel constructions of the Standard Model in global set-ups of type IIB Calabi-Yau compactifications. We argue that the Standard Model quiver can be embedded into Calabi-Yau threefolds through orientifolded D3 branes at del Pezzo singularities dPn with n ≥ 5. To illustrate our approach, we explicitly construct three distinct local dP5 models via a combination of Higgsing and orientifolding. This procedure reduces the original dP5 quiver model to the Left-Right symmetric model with three families of quarks and leptons and a Higgs sector to further break the symmetries to the Standard Model gauge group. Subsequently, we discuss an explicit embedding of the local model in a global Calabi-Yau compactification. We show that moduli can be stabilised in 4-dimensional de Sitter vacua with uplifting provided by T-branes.
