Mathematical Analysis on Cold Dark Matter

AI Thread Summary
The discussion centers on the mathematical background of the Cold Dark Matter (CDM) model of the universe. It highlights that much of the field theory related to CDM remains speculative, with supersymmetry being a notable area of interest for potential dark matter particles. Participants note that while the Large Hadron Collider (LHC) may not directly detect dark matter, it could uncover high-energy particles that provide insights into the correct theoretical framework. The conversation emphasizes the need for further research and future dark matter searches to enhance understanding. Overall, the mathematical exploration of CDM is ongoing and complex.

Hi Guys,

Can anyone provide links, books which explain the mathematical background of the field theory that explains the current accepted ^CDM model of the universe?

Thanks

Unfortunately, a lot of the field theory surrounding CDM is speculative at the moment. One of the possibilities is that the dark matter particle is the lightest supersymmetric particle, so reading up on supersymmetry may be helpful for seeing one possible theory that might potentially include the dark matter particle. Just bear in mind that there are many other possibilities. Hopefully future dark matter searches or the LHC will provide further insight (the LHC is unlikely to detect the dark matter particle itself, but it may detect other high-energy particles that could give us a hint in what theory is correct at higher energies, which would tell us what framework we should use to try to understand dark matter).
 
https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...
Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
