Why "Quark"?
The name "quark" was taken by Murray Gell-Mann from the book "Finnegan's Wake" by James Joyce. The line "Three quarks for Muster Mark..." appears in the fanciful book. Gell-Mann received the 1969 Nobel Prize for his work in classifying elementary particles.

Physicists working on the ATLAS experiment at CERN have confirmed that the Higgs boson decays to two bottom quarks. The discovery was made by combining data from two runs of the Large Hadron Collider (LHC) and was announced today at the 2018 International Conference on High Energy Physics in Seoul, Korea.

Although this decay channel should account for nearly 60% of all Higgs decays at the LHC, it had proven extremely difficult to spot it amongst the vast number of particles that are produced by proton-proton collisions at the collider.

Predicted in 1964, the Higgs boson was discovered in 2012 at the LHC where it is produced in high-energy proton-proton collisions.
