I wonder what kind of proof we have that dark matter is really made of not-yet-discovered WIMP particles and not WISPy? [closed]
There is quite reasonable argument by Joerg Jaeckel that dark matter might be actually very light, very weakly interacting particles, so-called WISPs (for weakly interacting slim particles), as ...
I'm no expert in this stuff, it's just a hobby to me, but I've been reading up on the WIMP theory a bit - layman articles, not published research. From Wiki on Dark Matter: It also cannot ...
In their paper, "A Theory of Dark Matter" (http://arxiv.org/pdf/0810.0713v3.pdf), the authors in a section argue that if there is a massive dark matter particle $\chi$ which interacts via a force ...
I have some trouble in the interpretation of the WIMP cross-section annihilation versus their mass. I understand that the lines represent a upper bound on the cross section from the observation. ...
"Stable Higgs Bosons - new candidate for cold dark matter", by Yutaka Hosotani Has the hypothesis in the above article been proved? What about WIMPs?
As a dark matter candidate, what should be the temperature and kinetic energy (or also the speed) of the WIMPs (weakly interacting massive particles) to agree with the observed distribution of dark ...
