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 ...
Most simply, a native word can at some point split into two distinct forms, staying within a single language, as with English too which split from to. [3] Alternatively, a word may be inherited from a parent language, and a cognate borrowed from a separate sister language. In other words, one route was direct inheritance, while the other route ...
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.
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.
A legal doublet is a standardized phrase used frequently in English legal language consisting of two or more words that are irreversible binomials and frequently synonyms, usually connected by "and", such as "null and void".
Donald Trump was threatening to send Meta CEO Mark Zuckerberg to prison “for life” if he interfered in the election just a few short months ago—but come Thanksgiving, the bad blood appears ...
In today's puzzle, there are seven theme words to find (including the spangram). Hint: The first one can be found in the top-half of the board. Here are the first two letters for each word: WA. WA ...
"It had so many different genres mixed together that, truly, I thought, 'This could either be amazing or a f---ing disaster,'" Moore said of Ghost. "Either way, it's usually the kind of juice that ...
