 Doublet–triplet splitting problem

The doublet-triplet splitting problem is an issue that arises in particle physics, particularly in the context of supersymmetric (SUSY) theories. It refers to the challenge of explaining the mass separation between the lighter (doublet) and heavier (triplet) Higgs bosons in models that include supersymmetry. In the Standard Model of particle physics, the Higgs boson is responsible for giving mass to other particles via the Higgs mechanism.
