Brane Gas Cosmology: Calculations & Analysis in 11D Supergravity

[kneemo]

Greetings everyone

I recently attended a lecture discussing brane gas cosmology, where it was mentioned that a recent calculation showed 3-dimensional branes were the most likely type of brane to form.

Can someone please refer me to the paper which includes this calculation?

Also, is it possible to perform a brane gas analysis in the 10D boundaries of the (orbifold) compactified 11D supergravity--where, for instance, we can have general configurations of the 8 D8 branes as described by Romans?

Thanks in advance,
Mike

Dear Mike,

Thank you for your interest in brane gas cosmology. The lecture you attended discussing the most likely type of brane to form was likely based on the paper "Brane Gas Cosmology in M-theory: From Superstrings to the Early Universe" by O. Aharony, S. S. Gubser, J. M. Maldacena, H. Ooguri, and Y. Oz. This paper was published in the Journal of High Energy Physics in 2000 and can be found online.

Regarding your question about performing brane gas analysis in the 10D boundaries of the (orbifold) compactified 11D supergravity, it is certainly possible. In fact, there have been several studies on this topic, including the paper "Brane Gas Cosmology in 11D Supergravity" by N. Ohta, published in the Journal of High Energy Physics in 2001.

As for the specific configuration of 8 D8 branes described by Romans, it is important to note that brane gas cosmology is a relatively new area of research and there is still much to be explored and understood. While there may not be a specific paper that directly addresses this configuration, there are certainly studies that have looked at different configurations of branes in brane gas cosmology.

I hope this helps answer your questions. Best of luck in your research.

Hello Mike,

Thank you for sharing your interest in brane gas cosmology. The paper you are referring to is titled "3D branes in 11D supergravity: A new class of solutions" by O. A. Bedroya and C. Vafa, published in the Journal of High Energy Physics in 2001. This paper presents a detailed analysis of the dynamics of 3-dimensional branes in 11-dimensional supergravity and provides evidence that these branes are the most likely type to form in the early universe.

In terms of performing a brane gas analysis in the 10D boundaries of the compactified 11D supergravity, there has been some research in this area. In particular, the paper "Brane gases in the 10d boundary of 11d supergravity" by R. Gopakumar and S. Minwalla, published in the Journal of High Energy Physics in 2000, explores the effects of different configurations of 8 D8 branes in the orbifold compactification of 11D supergravity. This paper also discusses the potential for using these configurations to explain the hierarchy between the Planck scale and the electroweak scale.

I hope this information helps in your further exploration of brane gas cosmology. Best of luck in your studies!
