Dark Matter as a Yukawa Like 5th force?

[MTd2]

Just an idea:

Suppose dark matter has a repulsive force towards matter and dark matter which follows a yukawa potential. It would be consistent with the lack of it in globular clusters, galactic center besides its clustering in galaxies. In case it touches matter, it would just cause an elastic recoil.

What do you think?

Read the early papers on CDM cosmology in the 80's. Especially Blumenthal, faber, primack etc 84. And the other Primack papers.

Your idea, while creative, would break the C (cold) part.

Why breaking the cold part? It would be just WIMP cloud, orbiting the galaxy. Except that it would mostly avoid clusters of matter, like star systems, globular clusters but be located within the galaxy.

I looked for Primack and on this online review article:

He talks about a certain self interacting dark matter:

Well, this is not the sort of thing I am thinking about. I am talking about a 5th force really, that has a very long range. It wouldn`t get close to the core of the galaxy after its formation.
