        I’m not a particle physicist but my guess would be some sort of subatomic particle. this article gives some information http://www.livescience.com/23232-smallest-ingredients-universe-physics.html

        If you look it up the standard model, you will see that our entire universe is made of 12 different matter particles and four forces.
        On July 2012, the ATLAS and CMS experiments at CERN’s Large Hadron Collider announced they had each observed a new particle in the mass region around 126 GeV. This particle is consistent with the Higgs boson predicted by the Standard Model, and I think is the smallest particle observed so far.
        However, I think the Graviton is smallest than the Higgs boson but not yet observed.

        I think quarks
        (An elementary particle and a fundamental constituent of matter. They combine to form composite particles called hadrons, the most stable of which are protons and neutrons.)
