Question

What is HIgs Boson? how they use the resultant energy from the collison ?

Answer 1

its an imaginary particle which is supposed to be origin of all fundamental partical

Answer 2

It's a hypothetical particle, that we are nearly nearly certain it exists. It won't be the origin of all fundamental particles, but the origin of their mass. The energy of the collision is converted into particles which are like a fingerprint of the Higgs Boson. They are currently detecting these particles, and if they find the correct fingerprint, then we would know we have seen the Higgs Boson!
