Where is the model that would get all the measured couplings right?kodama said:could the higgs boson be the inflaton 126gev
I don't see how you would get that right with the much higher scale of inflation. On the other hand, I didn't check all the ~200 arxiv submissions that appeared so far.kodama said:if not could the possible 750gev diphoton be the inflaton?
See the various theory papers for predictions.kodama said:what are the properties of the inflaton?
Is that question based on anything?kodama said:could inflaton be scalar dark matter?

The observed value of the Higgs boson mass indicates that the Higgs potential becomes small and flat at the scale around 1017GeV. Having this fact in mind, we reconsider the Higgs inflation scenario proposed by Bezrukov and Shaposhnikov. It turns out that the nonminimal coupling ξ of the Higgs squared to the Ricci scalar can be smaller than 10. For example, ξ=7 corresponds to the tensor-to-scalar ratio r≃0.2, which is consistent with the recent observation by BICEP2.
There is currently no evidence to suggest that the Higgs boson can act as the inflaton, a hypothetical field responsible for the rapid expansion of the universe during inflation. The Higgs boson has been extensively studied and its properties do not align with those of the inflaton. However, further research and experimentation may shed light on this question.
An inflaton is a hypothetical scalar field that is thought to have existed during the earliest moments of the universe. It is believed to have caused a phase of rapid expansion known as inflation, which is responsible for the large-scale structure of the universe we observe today.
While the LHC has the capability to produce particles with a mass of 750 GeV, there is currently no evidence to suggest that an inflaton with this mass can be produced. Inflation is thought to have occurred at energies much higher than what the LHC can reach.
While there is currently no direct evidence for the existence of an inflaton, its existence is supported by various observations such as the flatness and uniformity of the universe, as well as the observed distribution of matter and energy. Further evidence may be found through experiments and observations of the cosmic microwave background radiation.
The Standard Model does not currently have a mechanism to explain the existence of the inflaton. This is one of the reasons why inflation remains a major area of research in cosmology and particle physics. The search for a theory that can incorporate the inflaton and connect it to the known particles and forces is an active area of study.
