1. Since then, QCD has been the established theory of the strong interactions . 2. This energy derives from the strong interaction , which is mediated by gluons. 3. Since baryons are composed of quarks, they participate in the strong interaction . 4. Asymptotic freedom was believed to be an important characteristic of strong interactions . 5. First, the strong interaction acts essentially among the quarks forming the nucleons. 6. However, there is no experimentally known violation of the CP-symmetry in strong interactions . 7. Applied to the strong interaction , it led to the development of string theory. 8. Quarks are the fundamental constituents of hadrons and interact via the strong interaction . 9. Centaurs have short dynamical lives due to strong interactions with the giant planets. 10. According to the Noether theorem, isospin is conserved with respect to the strong interaction .
