RE: Dark matter rising in the sun

in #steemstem6 years ago

Dark matter detection is a sneaky science :D
The Sun has got some of the interaction covered. Now, I see the work of the Sun in helping build a model. I'd like to ask if it is now a certain science that dark matter particles annihilate themselves.

Sort:  

As dark matter has to interact in some way (through gravity, or through potentially new forces), there will always be a possibility for it to interact and annihilate. Like electron-positron annihilation into photons, after replacing every involved particle by something dark.

Note that in the kind-of standard WIMP paradigm, dark matter particles will interact with some of the particles of the Standard Model (this could be one, 10, all, we don't really care). A consequence of these interactions are that:

  • dark matter can be produced from the Standard Model (like at the LHC were one collides protons)
  • dark matter will interact with normal matter (at the basis of all dark matter direct detection experiments).
  • dark matter will annihilate (we will get a relic density from the early days of the universe, as well as a dark matter signature in cosmic rays).

That is the standard. However, there are ways to go beyond (secluded dark matter, strongly-interacting dark matter, etc.).

That answers my questions and more :)
It is a fascinating adventure whenever you wake up and go to work as a particle physicist :D

I like it every single day... except when it turns out I only do admin and no physics :/

Admin job seems monotonous and boring :)

Not monotonous, but I feel I would prefer to dedicate my time to something else :/
