Discovery of antimatter by Paul Dirac rose a question: If there is
antimatter, why there is that negligible or hardly any amount of
it in the universe? The thing is, at instant of the big bang, all
antimatter annihilated with matter, but per every annihilation
one baryon survived in a billion. This is called baryonic
asymmetry.
It’s very difficult, currently, to create antimatter at CERN due to
very high energies at which antimatter is formed. During very
