Maybe they meant that cosmic rays colliding with the atmosphere could produce udQM? Cosmic rays are mostly just really energetic protons (just like what you get inside the Large Hadron Collider, but potentially with even more energy) and low mass atomic nuclei (like alpha particles).
- time-of-flight 8y agoNo, they mean that cosmic rays would be udQM (presumably produced somewhere in the universe and accelerated to us somehow). The premise of the paper is that you need a large number of quarks (for 300+ nucleon system, that's 900+ quarks) to start to enter this udQM regime of stability, and as you say cosmic rays typically have A<40, which is only 120 quarks...
