2. Doublet–triplet splitting problem - Wikipedia

   en.wikipedia.org/wiki/Doublet–triplet_splitting...

   In particle physics, the doublet–triplet (splitting) problem is a problem of some Grand Unified Theories, such as SU(5), SO(10), and . Grand unified theories predict Higgs bosons (doublets of S U ( 2 ) {\displaystyle SU(2)} ) arise from representations of the unified group that contain other states, in particular, states that are triplets of ...

3. SO(10) - Wikipedia

   en.wikipedia.org/wiki/SO(10)

   Unfortunately, this same 10 also contains triplets. The masses of the doublets have to be stabilized at the electroweak scale, which is many orders of magnitude smaller than the GUT scale whereas the triplets have to be really heavy in order to prevent triplet-mediated proton decays. See doublet-triplet splitting problem.

4. Georgi–Glashow model - Wikipedia

   en.wikipedia.org/wiki/Georgi–Glashow_model

   This is known as the doublet–triplet (DT) splitting problem: In order to be consistent we have to 'split' the 'masses' of and , but for that we need to fine-tune and . There are however some solutions to this problem (see e.g. [ 3 ] ) which can work quite well in SUSY models.

5. Doublet state - Wikipedia

   en.wikipedia.org/wiki/Doublet_state

   In quantum mechanics, a doublet is a composite quantum state of a system with an effective spin of 1/2, such that there are two allowed values of the spin component, −1/2 and +1/2. Quantum systems with two possible states are sometimes called two-level systems .
