    • 2016, Frank Wilczek, “Superheavy Light Quarks and the Strong P, T Problem”, in arXiv[1]:
      One can implement the "massless quark" solution in a phenomenologically acceptable way, by using a massless quark that is always confined within superheavy particles, and is therefore effectively superheavy: a cryptoquark.
