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

   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.

5. Georgi–Glashow model - Wikipedia

   en.wikipedia.org/wiki/Georgi–Glashow_model

   The caveat of this is that since the Higgs field is an SU(2) doublet, the remaining part, an SU(3) triplet, must be some new field - usually called D or T. This new scalar would be able to generate proton decay as well and, assuming the most basic Higgs vacuum alignment, would be massless so allowing the process at very high rates.

6. Grand Unified Theory - Wikipedia

   en.wikipedia.org/wiki/Grand_Unified_Theory

   These theories predict that for each electroweak Higgs doublet, there is a corresponding colored Higgs triplet field with a very small mass (many orders of magnitude smaller than the GUT scale here). In theory, unifying quarks with leptons, the Higgs doublet would also be unified with a Higgs triplet. Such triplets have not been observed.

   The US would hit the new ceiling in the second half of the year, with the potential of default coming in the first half of 2026, according to his back-of-the-envelope calculation.

8. 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 .
