Magnetotransport measurements in hBN-encapsulated MoS₂ reveal that the conduction-band spin-orbit splitting is larger than predicted by standard DFT. The discrepancy is resolved by combining DFT+U+V, which corrects band-edge hybridisation, with many-body exchange effects that further enhance the splitting.
