And just to add to this. All particle colliders are mater-antimatter colliders, it just doesnt work otherwise (charge conservation) Thats right, every single particle collider where you are annihilating the particle is matter-antimatter.
Now before somebody says, but the LHC is proton-proton, you suck, the LHC is actually a quark-anti quark or gluon-gluon collider. Protons are not just 3 quarks, due to the strong interaction there is also a sea of gluons and quark-anti quark pairs which carry the momentum of the proton. At the energies of the LHC, this sea becomes important.
The article is terrible and horribly confused. Reads like something from the Sun (a gutter British newspaper for non Brits).
