proton-proton interactions

Proton-proton interactions occur when two protons, which are positively charged particles inside atomic nuclei, come very close together and interact through the fundamental force called the strong nuclear force. This force binds protons and neutrons together in the nucleus. When protons collide at high energies, they can produce new particles, release energy, or sometimes scatter off each other. Such interactions are key in understanding the forces that hold atomic nuclei together and are studied in particle accelerators to explore the fundamental nature of matter and the universe.
