The LHC is not going to create WIMPs, Ivan.
Yes, dear Stephen, WIMPs are not dangerous, because they are very hypothetic and have no any observational prove.
But the dark matter has a large variety of reliable observational proves.
The mass of ordinary matter in the Galaxy is about by 5-6 times smaller than the mass of dark matter.
What is dark matter?
I think that one of a large variety of different types of fermionic and bosonic subnuclear condensates can be a much trustworthy candidate on the role of dark matter. These condensates can be in the form of microscopic droplets and also as extremely dense dark stars of different masses. What are they: magnetic holes, strange droplets/stars, 2-nd generation matter stars, quark stars, I do not know?
Can the ordinary matter be transformed into a dark matter?
Yes, and we can see such transformations as novae and supernovae explosions.
How the ordinary matter can be transformed into a dark matter?
1. By a collapse of usual star. 2. Transformation can be switched by high energy cosmo-cosmo collision of protons or ions. 3. Transformation can be switched by high energy cosmo-atmospheric collision of protons or ions. 4. Transformation can be switched by high energy collider collision of protons or ions.
Microscopic droplets of dark matter, created by cosmo-cosmo collisions of protons or ions, are very rarefied and can be swept out from Solar system by solar wind and light.
The ones, created by cosmo-atmospheric collision are decay because of being overheated.
Microscopic droplets of dark matter, created at collider, can explode the Earth and Sun.
The main thought is the following: the probability of creation of microscopic droplet of dark matter in Pb-Pb collisions is much greater than in p-p collisions, because in the first case there is no need to create a decaying anti-droplet. Look:
Pb+Pb -> D+leptons.
p+p -> p+p+D+D~.
D – droplet of dark matter (strangelet, or 2-nd generation matter, or neutronized strangelet, or charmlet, or other quark mixture, or magnetic hole).
D~ – decaying anti-droplet
Do not afraid of hypothetic WIMPS, but in a couple of weeks LHC will start HI-HI collisions, which can create one form of dark matter, which will explode the Earth. The duration of this explosion is of the order of 500-1000 days. The excessive flux of neutrino can be registered in a several days after the droplets creations. So, there is no need to wait for about 1000 days in order to know if LHC kill us or not. We will know it in November-December this year, if:
1. HI-HI collisions would be performed;
2. Online information about neutrino flux would be available;
3. Physicists would not lie about growing Solar activity or about Nibiru flying to us.
