Why doesn't the Higgs produces a cosmological constant

In summary, there is a discrepancy between the predicted and observed values of the cosmological constant, which is much larger than the expected value based on the standard model of elementary particles. This is due to the nontrivial quantum field theory vacuum, also known as the "vacuum catastrophe." The reason for this discrepancy is currently unknown.

If the vacuum contains all these Higgs bosons, at expectation of <246> GeV in vacuum, why isn't there a cosmological constant, given the vacuum an energy density of 246 GeV^4 , instead we see dark energy at a few meV^4. Could just say that the graviton doesn't couple to the Higgs at all, but doesn't that violate the
equivalence principle. Do we need another tachyonic world, which has a tachyo-Higgs at -246 GeV to cancel
out the vacuum energy? Is there any other way to solve this mystery?

It does, but nobody knows why there is a discrepancy between the predicted value of the comsological constant from the standard model of elementary particles and the experimentally observed value.

The discrepancy is much larger than what you indicated in your post, due to the nontrivial quantum field theory vacuum:

1. Why doesn't the Higgs produce a cosmological constant?

The Higgs field is responsible for giving particles their mass, but it does not produce a cosmological constant. This is because the Higgs field is a scalar field, meaning it has a single value at each point in space, while the cosmological constant is a tensor, meaning it has different values in different directions. Therefore, the Higgs field cannot produce a cosmological constant.

2. Can the Higgs field be responsible for dark energy?

No, the Higgs field cannot be responsible for dark energy. Dark energy is thought to be a form of energy that is causing the expansion of the universe to accelerate. The Higgs field, on the other hand, is a local field that only affects particles in its immediate vicinity. Therefore, it cannot have a global effect on the entire universe like dark energy does.

3. Is there a connection between the Higgs field and the cosmological constant?

There is no direct connection between the Higgs field and the cosmological constant. The Higgs field is responsible for giving particles their mass, while the cosmological constant is related to the overall energy density of the universe. However, some theories suggest that the Higgs field could indirectly affect the cosmological constant through its interactions with other particles and fields.

4. Could the Higgs field change in the future and produce a cosmological constant?

It is highly unlikely that the Higgs field could change in the future and produce a cosmological constant. The Higgs field is a fundamental field and its properties have been extensively studied and confirmed by experiments. Any sudden changes in the Higgs field would require new physics and evidence to support it.

5. How does the Higgs field affect the early universe and the formation of structures?

The Higgs field plays a crucial role in the early universe by giving particles their mass and helping to condense matter into structures such as galaxies and stars. Without the Higgs field, particles would not have mass and the universe would look very different. Therefore, the Higgs field is an essential component in understanding the formation of structures in the universe.
