How do particle collisions reveal the Higgs boson?

[Abersman]

so they take the total energy of thos decays particles like quarks and add them to see how much energy they have, eventyally after millions of collisions they would find out if there was a higgs particle there?
is this kind of correct?

 

[Drakkith]

Pretty much. The Higgs Boson decays quickly but can only decay into certain combinations of particles. By looking at the products of the collisions we are able to see which decays have happened and which particles have been produced, even though the initial heavy particles have already decayed before we could directly observe them.
