Top Quarks are the preferred particles, but are not commonly found in nature. Top quarks can be formed through the collision of gluons. Gluons and up and down quarks are found in protons, so by the collision of protons we can collide gluons. How do we see the Higgs?

9 Two gluons are collided to form top quarks which are then used to generate a Higgs. Higgs decays into W-boson pair. Which then decays to photons. Higgs decays in bottom quark pair. Which then decays to photons. http://www.nature.com/nphys/journal/v9/n5/fig_tab/nphys 2619_F1.html

(UC Berkley) Formation of W-Boson Pairs. (Dreiner) Determining the mass of the particle that would generate the different events. Ruling out known particles that would generate other events. Looking for the “anomaly.” (BBC)
