Not a physicist, but that actually happens. Depending on the coupling strengths between the various kinds of particles respectively fields and the amount of energy they have, different particles get created with different probabilities. That is why the Higgs is so hard to detect - for every Higgs you produce billions and billions of other particles that are easy to create and you have to look for the one Higgs in all this mess. Physicists calculate the expected amounts of other particles with incredible precision, subtract that from the experimental results and if they are successful they end up with a tiny amount of unexplained stuff.
