Dark Matter from an experimental point of view
نویسنده
چکیده
If Weakly Interacting Massive Particles (WIMPs) are the Dark Matter in the Galaxy, they can be detected directly in nuclear-recoil experiments or indirectly by observing their annihilation products. Limits obtained by the two techniques can be compared but this comparison requires some hypothesis about the WIMPs cross sections on nuclei and their annihilation branching ratios into neutrinos.

متن کاملFlavor Constraints on New Physics
This talk highlights, from a theoretical point of view, some recent exciting results in flavor physics, as well as future prospects. We discuss possible implications of a subset of the experimental results in tension with the standard model, such as the 4σ deviation in the B→ D(∗)τν̄ decay rates, and recent improvements in the constraints on axion portal dark matter models. We use the examples o...
متن کاملDark matter distribution function from non-extensive statistical mechanics
We present an analytical and numerical study of the velocity distribution function of self gravitating collisionless particles, which include dark matter and star clusters. We show that the velocity distribution derived through the Eddington’s formula is identical to the analytical one derived directly from the generalized entropy of non-extensive statistical mechanics. This implies that self g...
متن کاملClustering of Dark Matter Halos on the Light-cone
A phenomenological model for the clustering of dark matter halos on the light-cone is presented. In particular, an empirical prescription for the scale-, mass-, and time-dependence of halo biasing is described in detail. A comparison of the model predictions against the light-cone output from the Hubble Volume N -body simulation indicates that the present model is fairly accurate for scale abov...
متن کاملWIMP annihilation and cooling of neutron stars
Since Zwicky proposed the problem of the ‘‘missing mass’’ in 1933, a lot of theoretical and experimental effort has been made in order to unveil the nature of dark matter. Today, WMAP has provided very accurate data regarding the matter density in the Universe [1]. The energy density of the Universe is composed of 4% atoms and roughly 22% dark matter. Data from recent observations indicate that...
