AB  - We report on the investigation of proximity-induced spin–orbit coupling (SOC) in a heterostructure of bilayer graphene (BLG) and tungsten diselenide (WSe2). A BLG quantum dot (QD) in the few-particle regime acts as a sensitive probe for induced SOC. Finite bias and magnetotransport spectroscopy measurements reveal a significantly enhanced SOC that decreases with the applied displacement field, distinguishing it from pristine BLG. Furthermore, our measurements demonstrate a reduced valley g factor at larger displacement fields, consistent with weaker lateral confinement of the QD. Our findings show evidence of the influence of WSe2 across BLG layers, driven by reduced real-space confinement and increased layer localization of the QD states on the BLG layer distant to the WSe2 at higher displacement fields. This study demonstrates the electrostatic tunability of the spin–orbit gap in BLG/WSe2 hetero
